Just a little addition to the subject of extensions: I'd very much
like to add lexical-let and lexical-let* as another set of
extensions, because this gives the possibility to use "fast" lexical
variables without the dynamic-scoping-fluid-pain.
Currently, I did implement some control constructs that could be
done as macros still in the compiler directly (like prog1 or dolist)
because there I can make use of lexical helper variables; lexical-
let would allow using this feature directly from elisp (and
implementing these constructs equivalently as macros).
So, what do you think about this extension?
Is this modeled on the lexical-let work being done for Emacs (probably
to be merged for Emacs 24)? If so, I wouldn't call it an extension so
much as being compatible in advance. :-) And if not, you should
probably take a look at that work and make sure yours is compatible.
It definitely sounds like a good idea to me.
