[Template-haskell] Defining a function and using it in a splice within the same module

[Alfonso Acosta]

Hi,

The user guide from latest GHC release makes clear that doing what I
wrote in the subject of this message is not possible:

>From 7.6:

"You can only run a function at compile time if it is imported from
another module. That is, you can't define a function in a module, and
call it from within a splice in the same module."

Unfortunately I have encountered this problem more times than I'd like
while using TH to implement a DSL. My usual solution is to generate a
function to process the extra arguments which cannot be passed to the
splice (i.e. push the arguments out of the splice so that I can use
functions defined in the same module).

Nevertheless, I'd like to know if there are any chances of seeing this
problem solved anytime soon.

Thanks,

Alfonso
