reasons are two-folded: haskell is more powerful language. in
particular, there are lots of generic programming approaches besides
TH.

and then you followed that up with a post with which I fully agree.
Jacques
but my impression is that while TH itself is
typed--it's just more Haskell after all--it doesn't do much to prevent
you from generating code that is not well-typed.
Hi all,
I would like to learn a little bit more about metaprogramming in
Haskell. And I'm also wondering why metaprogramming is used much more
in Ocaml than in Haskell.
Camlp4 (Ocaml's metaprogramming facility) doesn't seem to much more
powerful that Template Haskell. The former is celebrated in
aditya.siram:
