Your example is as wrong as Froggie's answer, if this code makes sure the variable is always set, then it needs something to make sure the hash table is also always there, this has no end.
He probably didn't want to use a %variable because it's (wrongly) considered 'bad' (you know, the "don't use global variable, use an hash table instead").
I think /hrename and some /hcopy would be welcome, if I never had to rename an hash table, making a copy of it would have been useful for me in the past, I don't want to hijack this thread but copying only the matching item/data etc could be quite useful.
