User-defined literals (Extended literals) of C++0x... what compiler does support it?

Question

In other thread I introduced some techniques we would use for Model-Driven-Development in C++ once the C++0x, in particular user-defined literals, is available. I just revised the plans for GCC 4.5 and even 4.6 and it shows that this particular feature is not supported.

Anyway, do you know if I even have any compiler to test that feature to start designing/implementing the algorithms till the C++0x is approved and implemented in widestream free compilers (LLVM, GCC)?

Answer 1

None yet, as far as I know.

Answer 2

Not yet, although patches for both Clang and GCC have been submitted and rejected for reworking, so you should see something soon.
