[Haskell-cafe] Locate errors in TH for Haskell code

I have a task to convert one Haskell expression to another.
And I'd like to report errors properly.
[interpret| -- error reported here
valid haskell code
invalid code <- error
I can parse it with haskell-src-exts or haskell-src-meta.
but if I have error in the code (type-check) error is positioned on the
first line of the QQ-expression.
Do you know is it possible to report error at the line where it has
to keep original source code location in the Exp.
In the function I do transformation Exp -> Exp.
Or maybe there is a better way to do it instead of QQ?
