[Haskell-cafe] Slow Text.JSON parser

[Sigbjorn Finne]

Maybe. Handling the common cases reasonably well is
probably worth doing first (+profiling) before opting for
a heart&lung transplant..

To wit, I've trivially improved the handling of string and
integer lits in version 0.4.3 (just released.) It cuts down
the running times by a factor of 2-3 on larger inputs --

Not saying that there aren't additional wins to be had :)
