After all, current cvs ihc doesn't generate proper context declarations.
For example,
ihc --tlb ... <third party com server dll> generates (incorrectly?)
something like:
getStartDate :: TimeSheet a1
-> Prelude.IO a0
while hdirect 0.19 ihc generates (correctly?):
getStartDate :: (Automation.Variant a0)
=> TimeSheet a1
-> Prelude.IO a0
ghc 6.0.1 can compile the latter but not the former, complaining:
Could not deduce (Automation.Variant a0) from the context ()
arising from use of `Automation.outVariant' at ...
Probable fix:
Add (Automation.Variant a0)
to the type signature(s) for `getStartDate'
Not to mention this error is pervasive in the current cvs ihc generated
code.
