I guess I don't consider $value if 0; a trick. The idea is that, if sub initialize wants to have its use of $value be bound to the outer lexical even after that lexical's scope is exited, it needs to explicitly mention it. scalar($value); works as well, as does 0 if $value;.  Any of them should be accompanied by a comment. If you want to be pedantic, the latter is best documented as not triggering a 'Useless use' warning.
