( #3333=superdoc: print w/ replies, xml ) Need Help??
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().
