---------------------------------+------------------------------------------
There are a handful of functions in the `template-haskell` package, module
`Language.Haskell.TH.Lib`, that are defined in that module, but are not
used, and are not exported by the main Template Haskell interface
`Language.Haskell.TH`.
I propose to nuke them. I assume no one is using them (since they are not
exported by the main interface), and I'm not keen on the API of `rename`.
Moreover, `rename` becomes signficantly more compilcated with the advent
of view patterns.
The functions are:
{{{
combine :: [([(Name, Name)], Pat)] -> ([(Name, Name)], [Pat])
-- Seems to be a helper for rename
rename :: Pat -> Q ([(Name, Name)], Pat)
genpat :: Pat -> Q ((Name -> ExpQ), Pat)
alpha :: [(Name, Name)] -> Name -> ExpQ
simpleMatch :: Pat -> Exp -> Match
-- This is the most defensible; it's a "smart constructor"
}}}
Deadline 2 weeks.
