Re: symbol-macrolet clobbers (match-data), bug or feature?

[Richard Stallman]

This is an interesting idea, but I'd rather it be implemented in a way
that does not require loading CL, and not using symbol-macrolet.

One way to do that is to write a list of variables to bind to certain
match values, like this:

(r=~ "\\(abc\\)\\(efg\\)?" "abcefg"
     ((s0 b0 e0) (s1) (s2))
   (list (match-data) b0 e0 s0 s1 s2))

which would be equivalent to your

(r=~ "\\(abc\\)\\(efg\\)?" "abcefg"
     (list (match-data) <0 >0 $0 $1 $2))
