There's no doubt that hand-written language adapter libraries are less noisy than those generated by a tool such as SWIG. The thing is, debugging tool-generated adapter code is typically more category-based than individual use-case based.

IMHO, both approaches have merit depending on the situation. I lean towards using SWIG until and unless the situation warrants a hand-written solution due to the boilerplate nature of these types of libraries.
