(How does this combine with the "D ABI" anyway? I know binary
compatibility between the different compilers is a bit of a pipe dream
at the moment, but the only way that could work would be to standardize
any and all shuffling of class fields...)
Interesting observation.
But you don't necessarily need to standardize the shuffling algorithm.
If the offsets for fields in a class could be resolved at link time
(the compiler could dump the offsets in the object file), then the
linker could arange the final executable for any layout. The same could
be done for virtual functions too, giving us a true non-fragile ABI
capable of supporting changes in the order of member fields and
functions.
