Sure but this is about constexpr, not modules.

Modules implicate the entire toolchain, backward compatibility, and binary compatibility. constexpr is a compiler feature. Wild that they are being compared.

See how many years it takes for a compiler on average to be 100% compliant after a standard is ratified, not widely at all when one wants to write portable code, regardless.

In practice it's the same thing with C++ today as it is with web standards: you have to evaluate support on a feature-by-feature basis, and stick to the features that are supported on all the implementations you care about.

And constexpr in stdlib is much more likely to get quick adoption across all implementations than something like modules.

Not really, folks have done a good job turning the Web into ChromeOS, there is only one relevant browser still standing.

[int_19h]

Safari/WebKit is still very relevant, and it's quite different from Blink even if they have shared origins.

[mkoubaa]

I'll buy this when people who write web pages for a living exclusively support Chrome

[pjmlp]

Indeed, however there is a certain velocity how many years after the standard gets ratified until the compilers get fully compliant.
