It sounds like bashing.

Here's my unfinished, but working code, interfacing Google Apps Script to Purescript https://github.com/kika/purescript-google-appsscript/tree/ma...

Please tell me what is so _dead_ in it.

Though I'm pretty new to Purescript and to the Haskell world in general, it took me almost no effort to write this code once I figured out how Data.Function (renamed Data.Function.Uncurried in the latest Purescripts) works. Probably your issue with Purescript FFI was about not being aware of these helpers (which don't do much help per se, but remove ugly clutter of nested functions in JS code).
