learn about gd and gD those are not perfect though.
Also keep in mind that # * start searches on words.
They all are not language aware so they are only bad replacements for
what you're looking for.
If you compile with warnings doesn't ghc emit warnings about shadowing ?
If so names tend to be unique such those searches tend to be helpful.

I only know about scion which comes closest to what you ask for.
