--- Comment #56 from Rafał Mużyło galtgendo@o2.pl --- I wonder how the authors of this engine stumbled upon this implementation detail, as more I google for it, more it seems to not be documented anywhere...
Also, on a tangentially related topic: winedump's c++ demangling kinda sucks (that is seems to fail more often than not)...
