Well then functions with side effects should be more resonable than to
make procedures into functions.
But one could also simply use a function here and return "" if the
parsing failed and then simply check if my_username /= "". You have to
do if my_result then anyway so there is really not much difference to
the code. However I would have concidered throwing an exception in the
case the parsing failed.
