Re: Regex to check for beginning character

You don't need a regex for an exact match like this.

foreach(@lines) {

    if ( index( $_, '#' ) == 0 )
    {
        print "yahoo!";
    }
}

That's much faster than using a regex for this.

And of course you can simplify this to `foreach(@lines) { print "yahoo!" if ( index( $_, '#' ) == 0 ); }` [download]	[reply] [d/l]

That's not simplification. You're trying to win style points, but that's not how it's done (use parens only when neccessary) :) `for(@lines){ print "yahoo!" if 0 == index $_, '#'; }` [download]	[reply] [d/l]
