#5555: support qualified names for invoking a quasiquoter
---------------------------------+------------------------------------------
Reporter: nfrisby | Owner:
Type: feature request | Status: new
Priority: normal | Component: Compiler (Parser)
Version: 7.0.3 | Keywords:

---------------------------------+------------------------------------------
Consider
{{{
module M
import qualified A (qq)
import qualified B (qq)
}}}
In 7.0.3, the quasiquotation syntax `[A.qq|...|]` is rejected with
{{{parse error on input `A.qq'}}}.
Because of the stage-restriction, the only option is to create an
auxiliary module
{{{
module AB where
import qualified A; import qualified B
qqA = A.qq
qqB = B.qq
}}}
and import that into `M`. This is a pretty heavy-weight workaround.
Is there a reason qualified names are disallowed for invoking a
quasiquoter?
