D as A Better C?

I found it manageable to write bare metal code with stock LDC and 
no additional options. It doesn't require C runtime, malloc is 
only 6 lines and returns ubyte[] already. LDC actually had 
-noruntime option, which was only getting in the way. Some 
functions from druntime are useful, e.g. _d_array_cast_len, which 
allows simple casting between different types of buffers.

I use bounds checks, and they call _d_array_bounds, which takes 
ModuleInfo as a parameter. How it would work?

I think asserts are sort of useful.

I didn't try to use objects without GC, but don't see any 
particular issue.

Not urgent: LDC already allows me to use D without druntime, 
phobos and C library.
