Clarify Data.Data documentation

Authored by dfeuer on Sep 6 2017, 7:54 PM.



Explain much more clearly when dataCast1 and dataCast2 can
have non-trivial implementations. On a couple different occasions,
I have attempted to write better defaults for these, only to
discover that we can't really do that. The new documentation
implicitly explains why that is.

It doesn't look like this will be formatted properly.


Shouldn't this be a Haddock code block?
