2/ If I define in a module:

j = 3

and then define in another module:

------------------- h x = $([|j|]) main = do print $ h undefined -------------------

I obtain "3" as expected.

However, I do not achieve to make this system work with an infix declaration:

infix $([| j |]) +

I obtain:

parse error on input `$('

I don't know what happens exactly, but one way to get out of this problem is to write the complete top-level declaration with a splice, instead of only the fixity level: $(return $ [ InfixD (Fixity $([| j |]) InfixN) (mkName "+") ]) Concerning my first question, I have not been able to understand what happens at this time. I continue to look at it. Thanks, TP
