SRFI-26 (cut & cute) and slots in subexpressions

Hello,

I was looking through the discussion archive for SRFI-26, but
couldn't find any explanation why slots (<>, <...> ) are not allowed in
sub-expressions.
E.g. (cut * <> (+ <> <> ))

I understand that part of the idea was to keep things simple, but
extending the macro to cover sub-expressions seems (?) simple..

thanks,
Daniel Faken

The place to ask this is probably the SRFI 26 post-finalization list.

(I also don't think it's quite so simple---you might try your hand at
an implementation, and possibly post another SRFI.)
