:InteroTypeGeneric does not work with ghci backend

[gilligan]

I am using intero-nvim with ghci as backend provider (ghc 8.22). When I execute :interoTypeGeneric I get:

*Lib> :type-at "src/Lib.hs" 51 1 51 10 startApp
Couldn't guess that module name. Does it exist?   

The correct invocation for ghci would be:

*Lib> :type-at Lib 51 1 51 10 startApp

Note that :InteroTypeInsert works because it does actually use that syntax. My guess is that the invocation for :InteroTypeAt should be the same as for InteroTypeInsert and this would fix the problem?

After a lot bit of stuffing around, I was able to get something working (which means also cabal new-* now works as well). There's probably a better way by modifying the intero-neovim plugin, but this does what I need:

" Load up the current file in ghci (which magically works with cabal new-build) to - requires .ghci file (either project or global) to include `:set +c` ghc option
let g:intero_backend = { 'command': 'ghci', 'options': '-Wall -i ' . @%}
