Yes, that was what I meant. We intend to provide both libphobos and libtango
(libgphobos and libgtango for GDC), since the template issues no longer
seems to be a problem. There are some interesting linker issues with DMD,
but that's more in the ld interaction area and should be easily fixable
once I post in bugzilla :)
