Hi, all, a little while ago I uploaded haskeem 0.7.0 to hackage: this is my small scheme interpreter. I had been busy with other important stuff for a while, and hadn't worked on it for a while; but I've now updated it to build ok with ghc 6.10.3 + haskeline, plus I added a simple macro system; that had been one of the two big items left on my list for it. It's not yet full R6RS Scheme hygienic macros, but I'll get there, too... I had kind of a "functional programming moment" while doing this macro system... I had been thinking and reading about it for, oh, a couple of weeks now, and today I sat down to start that, with the hope of maybe finishing it in a week or two. Nope! All in all, it took about 45 minutes, with the really important changes to the code spanning, oh, call it a generous three lines of code. There were changes in 50ish other lines, but those were all pretty trivial, just adding another data type. Such a let-down! :-) :-) :-) There is one small regression in all of this, namely that with haskeline I have lost the ability to interrupt the interpreter and land back at the "lisp>" prompt. I can interrupt it all right, but I end up at the shell prompt... not so good! I know all that stuff can be set up to interrupt a little less thoroughly than that, I just haven't got around to it yet... soon, I hope. Uwe
