Yes, I tried that, but unfortunately it falls over with:

    Not in scope: data constructor `CharConstr'
cabal: Error: some packages failed to install:
template-haskell- failed during the building phase. The exception was:
exit: ExitFailure 1

In the version of Data.Data on my machine there does not appear to be
a CharConstr.

It looks to me like there is an incorrect dependency in Template Haskell.

I can see from the hackage build logs that I'm not the only one who
has this problem. I will report a bug.
