Second- Did you use strict?
use strict requires an element of discipline in your coding, but it also catches a number of common problems.
use strict 'refs'; $ref = \$foo; print $$ref; # ok $ref = "foo"; print $$ref; # runtime error; normally ok
These are otherwise legal perl that will help you to hang yourself if you aren't careful.
