Yet, probably 98% of programmers don't care of that. Like most programmers of C#, Java, Python, Perl, Lua, Ruby, Tcl, etc. I'd like to have a D compiler written in D, but there are more urgent/important things to do, I presume.

Creating a back-end requires lot of work, so it may be better to use the one of GCC and LLVM, and save your time to improve the language itself.

And another possibility is to use D1 to write a compiler for D2 :-)

There is also a full Python interpreter (and JIT) written in Python in the works, it's named PyPy.
