Maybe String -> CoreExpr in a GHC plugin

[Joachim Breitner]

Hi,

in a GHC plugin, I want to synthesize simple data structures, and
insert them into the code. What is the most idiomatic way of writing a
function, say,

  foo :: Maybe String -> CoreExpr

or

  foo :: Maybe String -> CoreM CoreExpr

so that the resulting CoreExpr describes the input. Abstractly
speaking, I could imagine creating the Core AST by hand (but I’d have
to figure out how to resolve the names of the constructors), or somehow
invoking the renamer, type-checker and desugarer from within CoreM.

Surely someone else has solved this problem before. How did you do it?

Thanks,
Joachim
