What makes you thing that there would be only one such high-level
library wanting to define a floatN type?
There is no such thing as a global namespace in D (well, one
could probably argue that the things defined in object are).
Thus, I don't see a problem with re-using a name in a third-party
library, if its a good fit in both places – and you'll probably
have a hard time coming up with a better name for SIMD stuff than
float4.
If at some point you want to mix types from both modules, you
could always use static or renamed imports. For example, »import
lowlevel = std.simd« would give you »lowlevel.float4
upVector;«, which might be clearer in the context of your
application than any longer, pre-defined name could ever be.
True, we shouldn't generally pick very likely-to-collide names by
default just because we can so, but denying the existence of the
D module system altogether is going to set us back to using
library name prefixes everywhere, like in C (and sometimes C++)
code.
