This looks out of line with other code that's version dependent, Why the using in.languageImportContext?
That's done nowhere else in the parser. Why not just the original test?

There's a doc comment further up that needs to be updated.
* if clauseInterleaving is enabled:
* DefSig ::= id [DefParamClauses] [DefImplicitClause]
*
As far as Parser is concerned, clauseInterleaving is now enabled, so the grammar should reflect this.

The issue there is that we also need to check if -source is configured and if it is less than 3.6, we should require the language import. While in.featureEnabled(Feature.clauseInterleaving) only checks that there is an import statement, it doesn't check the source version. Feature.clauseInterleavingEnabled does both of them but it seems that the context doesn't contain that information and the in.languageImportContext does (which is exactly what in.featureEnabled does)

I will wait for #20895 to be merged before merging this PR |

this shouldn't be mixing source version with language import checks, they should be kept separate,
e.g. in the parser do
if sourceVersion.isAtLeast(`3.6`) || in.featureEnabled(Feature.clauseInterleaving) then

not sure to see why we should do that ?
edit: fewerBraces was stabilised in 3.3 and we do similarly:

ok, I guess its fine then, curious that in parser they just have Feature.fewerBracesEnabled without explicit using

Yea, I was currious too. I guess it might be a no-op as it is, therefore a bug ?

This has been decided to be included in the 3.6.0 release. |

should #21195 be a blocker for this? |
|
I don't think so. It only affects new code combined with Java code. It cannot break anyone immediately. We should fix it, though, for sure, but not a blocker IMO. |

okay, it was open as a discussion but I've made it into an issue, #21346 |
