Walter Bright has just released version 1.067 and 2.052 of DMD which
offers 64-bit support on Linux for the D language. Also there is a GDC
for version 2 of the language which is not handled in the current D
tool. I will do some development of a new D tool (based on the current
one that is in the

AFAIK, there isn't a way. You can only determine D2 vs D1.
It would be a good feature to add to druntime though.

Why do I ask? I was thinking about adopting a coding practice where I define
explicit interfaces for all public aspects of my classes, and then couples the
interfaces closely to unit tests. Then, whenever

I've been trying out D's new 64-bit compiler and a serious barrier to
using it effectively seems to be abysmal garbage collection performance
with large heaps. It seems like the time for a garbage collection to run
scales linearly with the size of the heap *even if most of the heap is
