I completely agree that const and shared issues are more important than SIMD,
given that they affect far more people and have to do with some of the most
frustrating bugs. So, I'm not sure that this work on SIMD is particularly
well-timed. But I very much doubt that it's a waste of time. It could really
help make D acceptable to some of the folks who would otherwise insist on
using C or C++ for efficiency. And it's definitely addressing the complaints of
some of D's users. Still, I'd very much like to see the remaining core
language issues resolved sooner rather than implement enhancements like this
right now.
Still, Walter perfectly has the right to decide on what he wants to
work. I understand that he saw implementing SIMD as an interesting
challenge, and if working on SIMD keeps things interesting for him,
that can only be great.
Fixing long standing bugs is boring stuff compared to that. Yes it's
important, but does it needs to be Walter doing it? Even for an issue
requiring a language change, couldn't someone design the language
change, implements it, and create a pull request for it? Then it'd be
up to Walter to look at it, ask for amendments, then accept it or
reject it…
Looks good in theory, but in practice this approach hasn't worked very
well for pull request number 3.
