C++ standard library is not based around a GC.
D promises both MM possibilities yet its standard library as of 
now based around GC.

You are talking about design. When it comes to implementation, 
last time i checked, not using standard memory manager also means 
not using standard library.

A big codebase on another language is a problem shared by most of 
us and that is by far the most significant. Yet i thought we were 
talking about "why not switch to D" rather than "why not switch 
to another language".
