in reply to rename files in directory with new extenstion

This does it in one line. Also I wonder if, in BIG applications, you might get a time saving by avoiding regexp? This is not a rhetorical question - I'd be interested to know. 

while($f=<*.old>){rename $f, substr($f,0,-3).'new'}

    This would not work for file with extensions longer than 3 characters (eg any .html file). Not that I really need to point that out...
