(This isn't a solution, I'm just trying to understand your situation a
bit better:) Where are these shared local variables defined? I mean,
if all your scripts have their own "local var1" statement then they
will all have their own independent var1, anyway - and you say that
the concatenation approach works semantically. Do your scripts have a
natural sequence in which they should be ordered, so you can
confidently have a "local var1" in one script, knowing that any other
scripts that refer to var1 will come later, not earlier?
