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"?)
