Hi,
I just pushed a patch into the repository that may break existing code. Here is the patch description:
Implemented LET and LET* by variable renaming, which provides the correct scoping semantics, and simplifies both the producing and the produced code.
Removed the "." and "[]" name-mangling conventions from symbol-to-js-string. Any code that uses symbols such as "foo.bar[baz]" will now issue a warning, and needs to be rewritten to use standard Lisp accessors. This is needed for variable renaming to work, and is an extension of the patch that eliminated the ".method" method-calling convention.
Thanks to Daniel Gackle and Dough Hoyte for opening my eyes to this technique, which was right in front of me all along.
This is a win-win situation for everyone involved (yes, even if it breaks your code, think of it as an opportunity for refactoring).
With this patch Parenscript is finally rid of the evil symbol-abuse conventions, which IMO is the only thing from the original design of Parenscript that can in retrospect be called a mistake.
Let me know what you guys think.
Thank you, Vladimir
