[Ecls-list] Macros impossible in compiled function

[Peter Enerccio]

Macrolet will make possible to do local macros, which are fine, but this is
not what I meant.
What I wanted is to define macros "safely", because the code is evaluated
in different thread with safe symbols, thus it is first saved
as lazy function.

Would it be possible (with regards to modification of defmacro), with any
internal (si) ecl functions/c functions (because I think its not possible
with ansi common lisp) to create macro
at any time (which could be registered in global environment).

Thanks.
