4235 – !in not working (D1)

According to the D1 spec !in should be a valid syntax, however the compiler outputs a syntax error when used. With a large enough code base the compiler crashes.

I think D1 spec is incorrect. "!in" isn't listed at D1 changelog.

The spec is a more authoritative source than the changelog.
But still, changelogs should be complete. A particular problem occurs if something's noted in the changelog, but then later it is reverted without being noted in the changelog. See issue 926 for an example.

Do you have a test case for the crash?

I should not have posted about that crash in this report because it's probably unrelated to !in. The way I can reproduce it in my code is if I modify a string mixin from !(something in arr) to something !in arr. I have not tried to make a minimal test case for it but a single const string with a mixin statement might be enough.

Removing the ICE keyword from this bug since it has no test case. I have tried many times to reproduce a crash, but there's no enough information.

fix Issue 4235 

!in was never intended for D1, I removed it from the spec.
