Sorry to be such a newbie, but I'm trying to figure out the following: - 1) how do I pass the undefined value from a template to a subroutine? In particular, I want a way to do something like [% foo.bar(x=>4, y=>5, z=>undef) %] 2) Template::Stash::get seems to return the empty string if it can't find a variable. Is there a way of distinguishing variables which are set to the empty string from variables which have never been set at all?
Many thanks, Simon McGregor
