Can you give any examples of this? I'm not saying it's not true, I'm just
curious as to why you
would venture into the realm of TH without a reason.
E.g. refer to the recent discussion of storable-endian.

Or look into package 'encoding'. It uses TemplateHaskell in order to
convert Text descriptions of character sets into Haskell tables. I think
the character tables could be simply rewritten to Haskell syntax, or they
could be parsed by a function, where the parsed content is unfolded at
compile time. It could even be computed at runtime, since it is only
computed once because of laziness.
