Hmm
Just occurred to me that you can actually do this with a preprocessor.
If we extract the template declarations to a separate module, then
it can happen something like this (I have corrected some errors in the
above code):
main.hs
import Language.Haskell.TH
import QList
import
Oh, and output is as expected:
./test
(1,2,3)
1
(1,(2,3))
((1,2),3)

Also (sorry for the triple-post!) I noticed that in the TH
documentation, it says:
Type splices are not implemented, and neither are pattern splices
This means, while we could write a preprocessor that would give us, e.g.:
x :: Set Int
x = {1,2,3,4}
We cannot splice in the right
