Explicit variable declaration

Yep, I get it and I absolutely love this about Python. What I don't
actually love is situation, where I misspell and instead of setting
one variable, other is created. This is why I would like to declare
variables first and say, that these are the only ones, that can be set
in certain function (the same with fields in a class).

I am finishing a small tool, that allows to create such declarations
in similar manner to Smalltalk declarations. I hope I can post a link
to it soon.
