-# Add A Method To A Struct
-
-Given a `struct` in Go, we can attach a method to that struct. Put another way,
-we can define a method whose receiver is that struct. Then with an instance of
-that struct, we can call the method.
-
-Let's say we are modeling a turtle that can move around a 2D grid. A turtle has
-a heading (the direction it is headed) and a location (its current X,Y
-coordinate).
-
-```go
-type Heading string
-
-const (
-	UP    Heading = "UP"
-	RIGHT Heading = "RIGHT"
-	DOWN  Heading = "DOWN"
-	LEFT  Heading = "LEFT"
-)
-
-type Turtle struct {
-	Direction Heading
-	X         int
-	Y         int
-}
-```
-
-We can then add a method like so by specifying the receiver as the first part
-of the declaration:
-
-```go
-func (turtle *Turtle) TurnRight() {
-	switch turtle.Direction {
-	case UP:
-		turtle.Direction = RIGHT
-	case RIGHT:
-		turtle.Direction = DOWN
-	case DOWN:
-		turtle.Direction = LEFT
-	case LEFT:
-		turtle.Direction = UP
-	}
-}
-```
-
-The receiver is a pointer to a `Turtle`. The method is called `TurnRight`.
-There are no parameters or return values.
-
-Here are a sequence of calls to demonstrate how it works:
-
-```go
-func main() {
-	turtle := Turtle{UP, 5, 5}
-
-	fmt.Println("Turtle Direction:", turtle.Direction)
-	//=> Turtle Direction: UP
-
-	turtle.TurnRight()
-
-	fmt.Println("Turtle Direction:", turtle.Direction)
-	//=> Turtle Direction: RIGHT
-
-	turtle.TurnRight()
-
-	fmt.Println("Turtle Direction:", turtle.Direction)
-	//=> Turtle Direction: DOWN
-}
-```

-# Sort Slice In Ascending Or Descending Order
-
-The [`slices.Sort`](https://pkg.go.dev/slices#Sort) function defaults to
-sorting a slice in ascending order. If we want to control the sort order, we
-have to do a little more work. We can reach for the
-[`slices.SortFunc`](https://pkg.go.dev/slices#SortFunc) function. This allows
-us to define a sort function and in that function we can control whether the
-sort order is ascending or descending.
-
-Here I've defined `SortItems` which takes a list of items constrained by the
-[`cmp.Ordered`](https://pkg.go.dev/cmp#Ordered) interface (so things like
-`int`, `string`, `uint64`, etc.). It takes a direction (`ASC` or `DESC`) as a
-second argument. It does the directional sort based on that second argument.
-
-```go
-import (
-	"cmp"
-	"fmt"
-	"slices"
-)
-
-type Direction int
-
-const (
-	ASC Direction = iota
-	DESC
-)
-
-func SortItems[T cmp.Ordered](items []T, dir Direction) {
-	slices.SortFunc(items, func(i, j T) int {
-		if dir == ASC {
-			return cmp.Compare(i, j)
-		} else if dir == DESC {
-			return cmp.Compare(j, i)
-		} else {
-			panic(fmt.Sprintf("Unrecognized sort direction: %d", dir))
-		}
-	})
-}
-
-// items := []int{3,2,8,1}
-// SortItems(items, ASC)
-// // items => [1,2,3,8]
-// SortItems(items, DESC)
-// // items => [8,3,2,1]
-```
-
-Because `slices.SortFunc` expects a negative value, zero, or positive value to
-determine the sort order, we use
-[`cmp.Compare`](https://pkg.go.dev/cmp#Compare) which returns those kinds of
-values. For ascending, we compare `i` to `j`. For descending, we swap them,
-comparing `j` to `i` to get the reverse sort order.

-# Disable Interpolation For A Heredoc String
-
-As a matter of convenience, a heredoc performs string interpolation by default.
-
-Here is an example of that.
-
-```ruby
-irb(main):087> word = 'taco'
-=> "taco"
-irb(main):088" puts <<-TEXT
-irb(main):089"   I want to eat a #{word}!
-irb(main):090> TEXT
-  I want to eat a taco!
-=> nil
-```
-
-A much less common scenario is that we don't want string interpolation to take
-place. For whatever reason, we want the exact string to be preserved. To
-achieve that, we can wrap the opening heredoc identifier in single quotes.
-
-As you can see, the `#{word}` portion is preserved.
-
-```ruby
-irb(main):091> word = 'taco'
-=> "taco"
-irb(main):092' puts <<-'TEXT'
-irb(main):093'   I want to eat a #{word}!
-irb(main):094> TEXT
-  I want to eat a #{word}!
-=> nil
-```
-
-This syntax puts the heredoc in single-quote mode. I left the IRB line preamble
-in for each codeblock so that you can see the difference. The first example
-(lines 88 and 89) shows the heredoc is double-quoted. The second example (lines
-92 and 93) shows the heredoc is single quoted.
-
-Note: the closing heredoc identifier (`TEXT` in this case) is not wrapped in
-single quotes, just the opening one.
