Oh! Good question. Unfortunately, I don't think Phobos modules
contain that information. The following line outputs 2076L:
pragma(msg, __VERSION__);
So, I guess I've been comparing apples to oranges but in this
case an older gdc is doing pretty well.
Doubt it. Functions such as to(), map(), etc. have pretty much
remained unchanged for the last 6-7 years.
Whenever I've watched talks/demos where benchmarks were the
central topic, GDC has always blown LDC out the water when it
comes to matters of math.
Even in more recent examples where I've been pushing for native
complex to be replaced with std.complex, LDC was found to be
slower with std.complex, but GDC was either equal, or faster than
native (and GDC std.complex was faster than LDC).
