[toronto-lisp] Pattern Matching in CL

[David Penton]

Do any of you have experience with pattern-matching packages in CL? By this I do not mean only regular expression stuff such as in CL-PPCRE, but rather pattern-matching for function definition as in Haskell, OCaml, the Racket match function, etc. (Although perhaps CL-PPCRE does this also;, but I am only familiar with the string-handling stuff in CL-PPCRE.)

My question is: If I want to mimic what is possible in Haskell, ML and kin, etc. what is the best CL stuff for pattern matching? I have looked at CL-MATCH but find the documentation a bit hard to penetrate. I am in a bit of a hurry to get something done that pattern matching would really help, so any recommendations are welcome.

Best,
