Despite the declared types, most 45 * of the functions provided operate only on branches of the type hierarchy. 46 * The declared parameter names are descriptive and specify which type is 47 * required.

For more detail, refer to LLVM's C++ code. 49 * If in doubt, refer to Core.cpp, which performs parameter downcasts in the 50 * form unwrap<RequiredType>(Param). 51 * 52 * Many exotic languages can interoperate with C code but have a harder time 53 * with C++ due to name mangling.
