LLVM is one of the best thing happened to D1, so maybe Walter can improve the situation, to allow a simpler/better attach of the D2 front-end to LLVM. If you keep your muzzle shut things will never improve. Maybe someone can write a list of all the points where D2 causes such port problems, so Walter may improve/fix them some.

This is quite important, more than most syntax details discussed in the last weeks.
