The following program invokes beta once instead of twice.
Extremely non-intuitive.
moving the #' down one line fixes it.
1) seems like it shouldn't compile.
2) $c is static and keeps its value between invocations if
one instead of if (0) one has if ($b)
This is boiled down from a real program, of course.
thanks,
Bruce

haven't analyzed this one thoroughly:
--cut 2--
use strict 'vars';
sub beta ($) {
my $a = shift;
print beta($a)\n;
xyz;
}
sub alpha ($$) {
my ( $a, $b ) = @_;
print alpha($a)\n;
# my $c;
my
$c = 1 if ($b);
$c = beta ($a) if ( ! defined $c );
}
alpha( 'A',0);
alpha( 'B',0);
