Any change I make to HyperTalk from now on is guaranteed to be upward
compatible. I might add new features, but I'll never break old
scripts. Therefore, I'll never require variables to be declared. I
may provide an optional way to declare them, perhaps with a type, so
that I can do type checking for you or, when I get to writing a
compiler, generate better code, but to uniformly require it would break
existing scripts. Similarly, I'll never disallow unquoted literals,
although I may provide a way for you to turn them off when you want
to.
