Well, if D has a specific calling convention, it's better for it
to give a lot back.

Regarding the LLVM back-end for Haskell, it has required a new
calling convention, used to replace a feature of GCC (missing in
D and in LLVM) ("Thankfully GCC offers an extension, 'Global
Register Variables', which allows you to assign a global variable
to always reside in a specific hardware register"):
