And yet, many code bases DO reinvent RTTI, for various reasons.
I work with code that is not allowed to depend on C++ runtime libraries,
so standard RTTI is out of the question.

Indeed, runtime allocation of unique identifiers is problematic.
But perhaps there is some kind of compile-time trick, apart
from manually assigning enums in some central header.
And ideally, portable across compilers so that foo.dll and
bar.dll would be consistant without being build by the same
vendor, or toolchains.
