That's good, but is rather a workaround for a limitation of the 
language. Is D the first language with a compiler unable to 
compile its own standard library? There is no guarantee in the 
language that one day even the most innocent operation in the 
language won't require the standard library and what compiles 
with "--no-runtime" today might as well not compile tomorrow.

In C or C++, while the standard library is part of the language 
standard, is not part of the language per sé. It is not part of 
the compiler, after all. It is provided with.

This will likely be the most limiting issue for the embedded 
world.
