The problems are technical.
It is for the ObjC++ maintainers to produce patches that do not adversely
affect the memory consumption, compile time performance or maintainability
of the C or C++ front ends. These are technical issues. If existing
slots in datastructures are to be reused, then all uses of those
datastructures in the existing front ends need analysing to make sure this
is safe (probably with checking added to the accessors to ensure it
remains safe). If new slots are added, statistics of performance on real
code are needed to show no statistically significant adverse effect.
Similarly, if conditionals are added anywhere someone thinks might be a
hot spot, profiling results are needed to show there is no performance
impact.
