This may well be the case, but you're missing the point:
Breakage is always bad, so we avoid it *unless* the change adds some
significant value to the language.
Fixing a bug (almost) always adds significant value.
Changing command line syntax, in my opinion (and, it would appear,
Walter and Andrei's) does not add significant value.
Although each individual person who suffers breakage may not care why
it happened, this does not in any way constitute an argument for
allowing less important changes to break stuff.
You seem to misunderstand what angers me and Jacob here. It is not the
fact that this specific DIP is rejected (I don't really care), it is the
fact that D developers keep repeating "D goes stable" mantra when it
actually does not. Pretending to prioritize stability and breaking code
even with bug fixes is technically lying. Bad for reputation, bad for
marketing. And good luck using "They have a different understanding of
stability" line in a dialog with enterprise type manager.
If stability is really a priority - please start doing something real
about it. At least start with defining what "stability" means and what
guarantees D team can give for users. Publish it at dlang.org and it is
at least a start.
Or stop rejecting stuff using "stability" as smoke screen. This two
options exclude each other.
I don't understand what you're sustaining. We all want D to become more
stable. It's not a smoke screen or a pretext to reject improvements.
My understanding of your reasoning is:
1. Stability is something binary, if you break some code no matter how
much code and on what grounds - if you break it stability is zero. If
you don't break any code at all, then stability is one. There is no
intermediate state between zero and one.
2. By definition (1), D is not stable.
3. Therefore since it's not stable, let's accept whatever changes
because they won't make anyone's life worse.
Is my interpretation correct? If so, do you understand reasonable people
may disagree with the reasoning above?
