Variable Length Arrays (VLA) proposal

One of the questions that need to be asked is whether it's OK to modify
the type in place like that. For Ada, we create new types with the
bounds fixed-up. I think you might run into problems with cached
values, such as the values accessible from the history (Eg: "print $2").
