The only problem I see is that linkers probably don't know what to do
with these sections, other than concatenating them. So when you have
the original names included, the object file size might actually grow
after linking, compared to a more traditional mangling implementation.

Of course, if that's the C++ ABI, linkers will learn to intelligently
combine these sections - which, in turn, might drop linker speed,
again.
