Actually, one language you mention there *is* worse than the others
for writing wrappable library code: C++. Admittedly, they've got a
Python interface now via boost, but the main problem with writing
wrappable C++ code is the template system and the inheritence systems
getting in the way. Symbol names aren't predictable and not
standardized, so it becomes impossible to write a portable system for
finding and binding to functions in a library. I've not yet found a
good way to do it in FFI code, and I would love to, as one library in
particular I hold near and dear -- OpenSceneGraph -- is entirely
written in C++.

I try to take things like a crow; war and chaos don't always ruin a
picnic, they just mean you have to be careful what you swallow.
