Possible solutions:
1. All the parameters of the block are local to the block.
   Well, this way programs written in past won't work.
   However you can pass values outside the block.
2. Ability to define block vars local
   How to define them local?
   Extra typing for future programs.

So either old programs won't work without modification,or new programs
need extra typing to avoid a probable bug. People will forget these
extra typings and create program bugs.

What about a version-marking system to provide compatibility?
Perl and some others have such a feature. You specify the version you
wrote your script for.
Next release will mark some old features depricated, and the version
after the next version will refuse to work?

So I think versioning maybe an acceptable choice (need 1 row extra
typing at the beginning of the program, or at the command line an extra
switch)
