	Three values? I'm only thinking two here, exists and does not exist.

	Now that I've read the code, the thing is that you already check if
something is defined, and then you check if its true. I just want to be
able to turn off the check if its true. I don't care if its true or
false, just if it exists.
	I don't see the point in taking whatever performance hit/complexity
filters and H::T::Expr introduce when what I want is already there :)
Also, does the H::T::Expr solution work with JIT?
