[Haskell-cafe] regular-xmlpickler

[Adam Bergmark]

Hi Grant,

This is an edge case since you have a field name with the same name as a
constructor. regular-xmlpickler doesn't try to treat this case differently,
I'm not sure if there is a good way to generically fix this in the way you
want.

That said, you can always write your own picklers using plain hxt to
flatten the structure, and note that you can mix custom instances with
regular-xmlpickler generated ones.

Also see the hxt-pickle-utils[1] package for a few helper functions

Cheers,
Adam
