well, if you solve the halting problem you could solve this too. :) perl
is so dynamic that the only way to know if a sub exists is to call it or
check the symbol table. subs can come into existance any time and be
handled by AUTOLOAD and such. so there is no easy compile time way to
check that at the moment. perl6 seems to be promising more than that.
