Re: 2: Improving the efficiency of this piece of code (&FUNC; vs. FUNC(); vs. &FUNC(); ? )

in reply to Re (tilly) 1: Improving the efficiency of this piece of code
in thread Improving the efficiency of this piece of code

I've made a habit of calling functions as &FUNC(); to make them more readily visible.

The following explanations would seem to approve my approach. Are there other factors I should take into account? Reason(s) why I should forego the preceeding "&"? Particular situations, perhaps?

perlman::perlsub tells me:
"& is optional with parentheses" and that "& makes current @_ visible to called subroutine".

perlman::perlvar says:
"within a subroutine the array @_ contains the parameters passed to that subroutine. See the perlsub manpage".

Update: After reading tye's post that Albannach linked below, and re-reading tilly's post above, I *think* I'm OK in continuing to &FUNC().
