receiver type with modifiers or annotations should be surrounded in parentheses on rendering: '(@A R).() -> T'
This also fixes stub builder tests (which check that stubs are consistent with rendered descriptors).
(required for 'suspend' on functional types).
TYPE_REFERENCE element now has MODIFIER_LIST child, which hosts annotations and modifiers for the corresponding type reference.
Annotations and modifiers written before an extension function type are now parsed as annotations and modifiers for the functional type, not the receiver type.
So, '@Ann A.(B) -> C' was '(@Ann A).(B) -> C', and became '@Ann (A.(B) -> C)'.
NB: DSL_SCOPE_VIOLATION testData updated accordingly.
Type projection variance modifiers ('in', 'out') belong to a separate modifier list under corresponding type projection (not under a type reference).
'A<in suspend T>' is 'A<(in (suspend T))>', 'A<suspend in T>' is an error.
In stub builder, create a modifier list node to host annotations and modifiers (none so far; TODO properly serialize/deserialize types with modifiers).
- There will be no `coroutine` keyword for builders
- They accept a special suspend function type instead
(it's return type is straightforward, not Continuation<Unit>)
- Instances of these types may be run with special built-in functions
- These built-ins functions are parametrized
with handleResult/handleException/interceptResume, so these operators
become unnecessary (and controllers too)
NB: `@Suspend` annotation is subject to replace with the `suspend` modifier
on types
- Introduce new 'rem' operator convention
- Prefer 'rem()' to 'mod()' when both are available, even if mod() is a
member, and rem() -- an extension
- Place operator 'rem' under the language feature
After this change SAM adapters are being resolved in the same group
as members, thus their overload resolution happens simultaneously.
But in the case of overload resolution ambiguity try to filter out all
synthetic members and run the process again.
See the issue and new test for clarification
#KT-11128 In Progress
'a<T>::foo' is reserved if 'a' is a simple name and can be resolved as an expression
(this can be extended to 'a.b.c<T>::foo' case, although that is rather hard to implement using PSI).
'a?::foo' is reserved if 'a' can be resolved as an expression.
For each platform declaration, there must be at least one impl declaration in
the module with the compatible signature; similarly, for each impl declaration,
there must be at least one platform declaration with the compatible signature.
Note that currently the presence of the 'impl' modifier is not checked yet.
Also, the sad fact is that if you have platform and impl declarations which are
not compatible, you get two errors: on the platform delcaration and on the impl
declaration. This needs to be addressed as well
Because PackageViewDescriptor may consist of several package fragments from
different modules (see LazyPackageViewDescriptorImpl#fragments), we now filter
out fragments from irrelevant modules before rendering them into the .txt
E.g. 'impl typealias Foo<A, B> = Bar<A, B>' is allowed; everything else
(variance, changing order of parameters, etc.) is pretty much disallowed.
This is done for simplicity: otherwise matching the platform/impl class scopes
would be not so straightforward
