I don't particularly care that the only recursive statements are #2,#3 - I just want my nice neat layout back. I have just spent an inordinate amount of time updating code when if the parser recognised "do rec" as a recursive group it would have been a drop in replacement and taken me one tenth of the time.
I think this would just require the lex layout rules already in place for do/let in GHC; my guess is that your example would work if the body were indented past the "r" of "rec". - -- brandon s. allbery [linux,solaris,freebsd,perl] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkweuP0ACgkQIn7hlCsL25XifQCgzvfvf9utQxkb2gdmVRPyhea2 iIUAnRT8XUhTKds0wrVkFaccyzAKTA9v =YjX6 -----END PGP SIGNATURE-----
