I believe in 4.6.1 it should still be possible to have the initialization
from components. All we need is to be able to write
complex(float __r, float __i) : _M_value{__r,__i} { }
or
complex(float __r, float __i) : _M_value({__r, __i}) { }
the work that people are testing really isn't C++03, it is C++0x.
It is fine if the C people don't want it. But in C++0x, we already
have the syntax (so no parser surgery is needed). All that remains is
to have the C++ front-end elaborate that syntax into the proper
initialization (ideal outcome) or a sequence of assignment (less ideal.)
Note that we already have that syntax for iniialization of array members
and a _Complex is supposed to behave like a 2-element array...
It is good that Richi is in the CC (as a RM) but, I suspect Jason should
be too.
