Following the approval of his DIP66, Igor Stepanov proceeded with an
implementation at https://github.com/D-Programming-Language/dmd/pull/3998.
Walter and I objected that the implementation is overly complex. My
opinion is much weaker than his; I'm not deeply familiar with the dmd
internals. Iain Buclaw seems to agree with Walter. and Igor has replied
with additional explanations for the added complexity.
As a result:
* We have no alias this
* The compiler is 2 KLOC smaller/simpler
* The PR has bitrotten
* Igor is probably frustrated
So this is a stalemate that I'd like to see broken. The best solution I
see with this is a core compiler contributor reviewing Igor's code and
either:
(a) Assuming Igor is still interested, give concrete, actionable
guidance to Igor so he can simplify the PR and follow through
shepherding the PR into dmd;
(b) If Igor is no longer interested, either take over the PR and modify
it for approval, or implement DIP66 from first principles;
(c) Review the code and discussion, and reach the conclusion the
proposed implementation is appropriate and no radical simplifications
are within reach.
Please chime in if you'd like to take this over.
Thanks,
Andrei
