GHC.Runtime.Eval.Utils

Split up a string with an eventually qualified declaration name into 3 components

1. module name

2. top-level decl

3. full-name of the eventually nested decl, but without module qualification

Example

    "foo"           = ("", "foo", "foo")
    "A.B.C.foo"     = (A.B.C, "foo", "foo")
    "M.N.foo.bar"   = (M.N, "foo", "foo.bar")

Qualify an identifier name with a module name

combineModIdent A "foo"  =  "A.foo"
combineModIdent ""  "foo"  =  "foo"
