Really? That's interesting
the code is like this:
case (requestMethod req, pathInfo req) of ("GET", []) -> index ("GET", ["object", pk]) -> getObject pk ("POST", ["object", pk]) -> jsonBody >>= updateObject pk _ -> bad status404 "no route match"
Hmm, that may indeed solve many of my use cases, and is very nice looking. I assume this only works with -XOverloadedStrings, and that's why you can pattern match on Data.Text? - -- Stephen Paul Weber, @singpolyma See http://singpolyma.net for how I prefer to be contacted edition right joseph -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAEBCAAGBQJPZTArAAoJENEcKRHOUZzedaEP/jzUSmrvTm6fWVpQOl9AOZoP UebR3RdwqUGXNXE7dPGgSkdihRsD8h0ToOHziNpphj7fVDLY216zSes6rL4GGZIq PL2HD6j0tW6GK/kQLwgYCoxNIy6v/E9FDppfuUDNNnPqloSIH4cTfvMVTLaVH434 yCR7bv202NckBeahmoFz/1xQh8pANijsrozNqz8vEifmzGbSt72/FqQ0d6oogOGk QEQFTy9ctjf1740paual/pn0v+ESIuTQ+0yxJ0wiaxowmaCHZdkqiTK3ZTZLpaB9 teqjrdGpxaYG6X9Ldv6ZzztphvrlfS57daBidxoelG8jaLX+f7SeNnbg8v9PX/31 JXJmEkkG5Nn2hkWUqw+9sNKcpJRzWqyx/hQyhPBKiPYGDtvyY0aB1UT7hoATzCPF QhPTVlyabx/53aKz6c7tXKrQGmRSQ1G163kJQzU682khhLUTvqL1u0ZFeEfdC3Bm bOo+K9+32pOBFCPee51pgy6cg0SRk/Z+8miGz6bzh2EJ+iaxGX2KkhlXFI+1G5Hu Cdnocehs0b1o9McAnHqAAgkrUov5HmY4akDkhzfbgP+4OgXtZn3j3nFlkU/MP46R Pi+ZQvjTVGtD0AEIwh5X1EKPYWx8cGZSIGTHxPTP3uZav59urLrYBmk/VcTTOWls Zt9s88iEIJ8Vgvm8V6P7 =i7R9 -----END PGP SIGNATURE-----
