[BAILOPAN]

Not much I can add here, since it's been said, but to reiterate: Yes, it's a pain. It sucks when stuff that worked stops working. It happens to me as a downstream developer on other projects, and I don't love it.

We work very hard on compatibility (something most projects do not do), which is why you can pull SM from 2006 and its plugins will probably still compile and work today. The amount of work to make Transitional Syntax happen - while still preserving the old declaration style - was insane. The parser is littered with dozens of mind-numbing hacks to make that work. I guarantee there are still bugs in it somewhere.

The number of people who actively work on SourcePawn is not zero, but it's less than 1, which is part of the tradeoff. Array-based enum structs were so poorly implemented and so under-specified that there was no feasible way I could keep them working while achieving other goals in my free time. Given I was able to add a straightforward replacement, and given you can use older compilers, I think it was a fair change to make.

If you're wondering, "what will break next?" Probably nothing. Array-based enum structs was the big baddie, and I think pretty much everything else in the language can be preserved going forward.
