I'm not sold on the extra parens used here -- I don't feel too strongly about it, but it's inconsistent with how `apply-partially' is called.
The author has mentioned that the reason for being a macro with extra parentheses was the ability to work with `eldoc`: inside the inner pair ofparentheses, we can look at parameters suggestion which is normally not possible
with `apply-partially`.`applying-partially` is bit confusing given the name of the existing function.
To differentiate it, can we name this macro differently? Like `any-partial-application`, `partially-apply-at_`, etc. -- Daanturo.
