Really? Please enlighten me....

I want to process an array of stuff @stuff. Lets say that I want to 
do a "tolower" on each element of stuff (an array of text strings).

The current way I do this is (yes I am a C programmer to the core):
                                        
for($i=0; $i<$#stuff; $i++) {
	$stuff[$i] =~ tr/A-Z/a-z/;
}

Is there a better way?
