I'd say it's a CPython thing. It is helpful to copy a lot of things from 
the reference implementation, but generally the lexical conventions of 
the C-API would seem ludicrous in Java, where scope is already provided 
by a class. And then there's the impossibility of a C-like pointer to 
byte. Names related to C-API have mnemonic value, though, in 
translation. Maybe "static void PyFloat.pack4(double, ByteBuffer, 
boolean)" would do the trick.

It makes sense for JyNI to supply it by the exact C API name, and all 
other API that C extensions are likely to use.
