You mentioned on the Github PR that this broke some Phobos (and
Druntime?) code. What was the extent of the breakage? If it's
small, I'd
say give it a year-long deprecation period and then be done
with it
forever.
The extent of the breakage is NOT among the top factors. Once a
piece of code goes from "compiles" to "doesn't compile" that
lowers the acceptance level by an order of magnitude. Only
after that, the extent of the breakage has any import.
Top factors:
0. Any silent breakages or changes in semantics? 100000000x
None in this case.
1. How frequent is the breakage? Is most code going to still
work? 100x
Very infrequent, judging by other peoples' repsonses here, and
the fact that there were only a handful of places in all of
druntime and Phobos.
2. How much does fixing the breakage improve code? Was the
breaking code incorrect for the most part? 100x
As I wrote elsewhere, my main motivation for the PR was enabling
a possible future tuple literal syntax, multiple return values,
unpacking assignment and the like. The gains were therefore not
so much in detecting wrong code, although apparently there is
some from time to time:
