Scot et al,
Just a point if clarification. The code we're supposed to golf must be
funcationally equivalent to:
if( $a ) {
$a = 0;
do_something();
}
## and now $a is false
Where were we told the do_something couldn't mess with $a? In which case
Ala's solution
$a&&do_something();$a=0
is the only one so far that works for all "do_something()"'s
Scot. Is $a guaranteed to be untouched?
