Hi, there.
Currently, variable names are very rigid. There are no ways to express variables other than by their actual name.
I *do* however, have it on the books and have a strong need for variable names that accept tokens as part of the name to be rendered at run-time. This, however, requires me to fix up the way tokens are parsed and allow nested tokens (this is a high-priority item, actually). So, once I have those two things in place, we can have stuff that simulates arrays... which means that VA will probably need to have scoped variables (not just global). Doesn't end LOL;)
