Adding extra returns makes it much more time-consuming for someone who didn't write the code to figure out what the return value of a routine is or means. (It also means extra code if you're using any debugging tools to check assertions or track runtime with code that executes at the start and end of important routines. Which I always do in Perl, because Perl has so little typing.)

In fact, about the only time I use goto is to goto the exit point of a routine. The necessary label will notify anyone looking at that code that there is some internal path directly to it.
