One other place that a little more explanation could be helpful 
is this sentence:

"It is written completely in D for LDC (LLVM D Compiler), without 
any assembler blocks."

It would be nice to describe (if it can be summarized in a 
sentence) why Mir GLAS relies on LDC and/or LLVM, and what 
differences in outcome can be expected if one uses a different 
compiler (will it not work at all, or just not as well?).

The broader topic of what compiler features Mir GLAS uses could 
be the topic of an entire blog post in its own right, and might 
be very interesting.
