Bigloo provides `match-case' and `match-lambda'.

Wright's matcher provides the same (but `match-case' is named `match')
plus more.

After a superficial look, it seems to me that the pattern language in
Wright's matcher is at the same more elegant and more powerful (and I
don't want to use the keyword `kwote'! :-).

Then, I generally have a very high respect for Andrew K. Wright and
his matcher seems to be of a later date.

(Bigloo's matcher could be faster, though, since it's generated from a
 partial evaluator.)
