Whether or not they are in the majority, a very large portion of PHP developers would prefer strict typing. In particular, the most vocal ones would seem to. There are also a lot of PHP developers who would prefer weak typing. Thus we have a problem: either approach to scalar hints will upset a large portion of the community. > >> Myself, I might have been somewhat happy with just weak hints, but >> it would upset an awful lot of developers who would like some measure of >> strict typing.

I'm sorry, but it makes no sense, especially given > the positive feedback you saw on internals, making it clear that there would > be in fact people using it. Not all of it was positive. Sure, a lot of people would use them though, but I’ve heard quite a few developers say they wouldn’t use them and continue to use manual (!is_int($foo))-style assertions. > If there's one thing that's worse than introducing an alien concept like > strict typing into PHP, it's introducing it as a feature that will include > all the negatives of this alien concept, PLUS have the ability to radically > change how it behaves based on a runtime option. This isn’t a runtime option, it is entirely compile-time. Much like namespaces are not a runtime option. There isn’t even the ability to toggle it at runtime, unless we somehow add some ability to edit the flags on individual opcodes.
