I tried LDC2 for Linux out last week and again last night.  I didn't spend much time on it on either attempt, but so far I haven't been able to get even Hello, World to compile.

If so, would you mind posting some instructions?  If LDC2 is, in fact, mature enough that it would be worthwhile, I'd like to test it out, file bug reports, etc.

I was even more self-torturing, I tried to compile it on Windoze twice I think. But it didn't really work.
Also I got the feeling that LDC2 has been hastily updated to the newest dmd frontend without verifying each upgrade step by step and now things are subtly broken.

LDC2 has a way to go before being D2 ready, gdc is far further along. From what I can gather, the following should compile ldc, druntime and phobos, it seems (very) broken currently though - best to get in touch with the guy working on it - I have a feeling he's using an old version of druntime.

hg clone https://bitbucket.org/prokhin_alexey/ldc2
cd ldc2
git clone https://github.com/D-Programming-Language/druntime
git clone https://github.com/D-Programming-Language/phobos
ccmake .
# type c, aet D_VERSION and RUNTIME_DIR, type c, set PHOBOS2_DIR,
# type c, type g
make phobos2

Scrap that, Alexy just replied with far better information!

The object module in druntime is always imported implicitly. You could try commenting everything in module object and reenabling things as you need them.
