Buu's code doesn't seem so bizarre - as many people have commented, it kinda makes sense.

But compare this: 

$s="a1 a2 a3";

for (1..2) { 
    print $1 if $s =~ ?a(\d+)?g;
}

with this: 
$s="a1 a2 a3";

print $1 if $s =~ ?a(\d+)?g;
print $1 if $s =~ ?a(\d+)?g;

I would expect these to be equivalent ... but no, the first example prints "1" and the second prints "1 2".

The plot thickens!

update 2004-06-04 01:41 - added conditionals so the first snippet prints "1" rather than "1 1".
