Add puts

Why

Hello. 👋

I keep running into situations where I'd like to use puts when swapping out an IO-like object (i.e. IO, StringIO, File, Kernel, Pathname, and so forth) and can't find any mention as to why Pathname#puts isn't supported as found in similar IO-like objects.

Allowing the use of Pathname#puts would make injecting IO-like dependencies behave similarly in terms of writing with a newline. This would allow anyone to more easily swap these objects out while still quacking like a duck so-to-speak. I bring this up because Pathname#write is supported but am confused as to why Pathname#puts is not.

How

Would it be possible to add Pathname#puts or is there some other reason why this isn't exposed? The workaround is to use Pathname#write by manually adding a new line each time. Example:

path = Pathname "test.txt"
path.write "Hi\n"

This achieves the same functionality but is tedious especially if you are not using a string literal each time. Example:

path = Pathname "test.txt"

# Tedious
path.write "#{some_computed_result}\n"

# Nicer (proposed solution) because you don't have to do the extra work of string concatenation.
path.puts some_computed_result

まず Pathname#write を見つけ、issue で挙げられている IO 風のオブジェクト上での puts と動作を比較します。Pathname が puts を公開し、呼び出し側が改行を手動で追加せずに値を書き込めるようになれば完了です。
