It's good to see that they chose the keyword discard instead of the underscore symbol. It's verbose, but at least you can see the damn thing.

The empty `discard` statement is a do nothing statement; it's not part of the type signature, if that's what you meant.

Ignoring a return value is a normal thing in many situations. I like verbose but "discard" is weird enough that it might complexify API design to offer two functions instead of a single one.

You don’t need two functions, you just mark one as {.discardable.} and the discard happens automatically. Unless I’m misunderstanding you.

`discard` isn’t part of the type signature.

The functions in the blog post have void return type because between `)` and `=` there is no `: [type]`.
