Sure, like I said in my previous message, ($$) acts as a shorthand for
Closure::fromCallable on any callable that takes one argument. But syntax for
getting a reference to a function has been discussed before, and it would be a
shame to be able to do it for this special case but not others.
Straw manning, if name::fn got a reference to a function from its name, you
could do:
$foo |> trim::fn
Which makes more sense than using a partial application operator without
applying anything.
