It's been suggested that DMD/LDC/GDC could be combined into a
bundle, say DCC, and when you call
DCC hello.d
it will call dmd hello.d,
and if you call
DCC -fast hello.d
it will call ldc hello.d or gdc hello.d
This will give newcomers a different experience.
I'm wondering if you couldn't achieve DMD's compilation speed in
LDC by turning off some of the optimisation passes for debug
builds. I understand that it will probably still be slower to
compile, but if it's a negligible difference, and the community
can fully support a single compiler I think that would be really
good for D as a whole.
