[Haskell-cafe] Errors with Template Haskell

[Jose A. Lopes]

Hi,

In Template Haskell, what is the proper way of signalling an error ?

For example, you are generating code and you detect that a given
parameter does not fulfill a precondition (e.g., String is empty), and
you want to abort compilation with a descriptive error message.

Thanks,
Jose
