ceterum censeo: good old C-linkage interoperability would be much more robust,
reliable and easier to maintain compared to the current UNO-bridges approach
of emulating the behaviour of the individual compiler, linker, dylib, unwind, etc.
environments and thus being extremely platform specific. What an incredible waste
of energy for little (if any) gain. SCNR.
