BTW, in GHC 6.2 with the -fglasgow-exts -farrows flags, you will be able to use either mdo or do...rec for monads and for arrows, as an experiment. (Maybe "rec" wasn't such a great keyword to take from the identifier space.)
"rec" is nice to have, but I think the "proc" notation also needs a corresponding "mproc" to do the automatic segmentation. The end programmers need not worry about extra "recs," it just adds another level of complexity (just like the let/let rec discussion). Ross: any plans on implementing that?
It's in the bit you re-quoted (not "mproc" but "mdo" inside "proc").
