> I think that `GHC.parseName` should return an empty list (with no error
message) if it doesn't find any bindings for the specified string. That
way the client of the API can complain if necessary. Once `parseName` has
returned a list of `Names` I think they should all be lookable up (using
`GHC.getInfo`) without errors.
yes, if `GHC.parseName` (and ghc api functions in general) could be made
to behave that way, it would help. i could then ignore that extra error
output in case i've already found module-related info.
there seems to be a third case, btw, failing to load interface:
{{{
