in reply to Re^2: To & or not to & ?
in thread To & or not to & ?

because only one of them does something different than FUNC()

Actually, all of them do something different as shown below:

> perl -le'@_=2;sub a($$) {shift or 1};print &a' 2 > perl -le'@_=2;sub a($$) {shift or 1};print &a()' 1 > perl -le'@_=2;sub a($$) {shift or 1};print a()' Not enough arguments for main::a at -e line 1, at end of line Execution of -e aborted due to compilation errors.

Sorry for the pedantry.
