Sure, like I said in my previous message, ($$) acts as a shorthand for Clo=
sure::fromCallable on any callable that takes one argument=2E But syntax fo=
r 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=2E

Straw manning, if name::fn got a reference to a function from its name, yo=
u could do:

$foo |> trim::fn

Which makes more sense than using a partial application operator without a=
pplying anything=2E
