Dear List,
Is it possible to have function names like ∀ (unicode universal
quantifier)?
This question is inspired by agda source code, which supports this.

It would be handy to use. My guess is, however, that it's not
supportet in R.
If you are willing continue to call it as `∀` rather than s just ∀,
then it seems to "work as expected".

[1] 2 3 4
Efforts to use the un-backquoted variants were failures for me:
> ∀ <- function(x) {x+1}
Error: unexpected input in "‚"
(Question: does your keyboard support such a character??? I.e, Why
would this be "handy"?)
