Specifically treat convertsTo of LogicalType to ClassifierType, support
convertsTo classifier type w/o specified classifier.
Fix typeOf LogicalItemValueExpression by to rely on logical's type.
Accept LogicalItem in LogicalItemValueExpression's logical slot to enable
replacement of it with an expression at generation time.
Drop node-ptr in node features, macro calls.
Drop node-ptr types in rule templates and recover closures,
fix BiConsumer params
Drop node-ptr// refs where appropriate.
Drop pointer operations from macro calls and term ctor's; add resolve to FunctionTypeLookup static table.
Drop node pointer operations from constraints, add require statements in SModel types macro table.
When inferencing the type of a closure within a method call context,
it's important to strip occasional contravariant indicator from the
closure's input variable.
A method may declare its argument to be an SMI with the type(s) of
its functional method's arguments as ? super T to facilitate subtyping.
This must not affect the inferred type of the closure's input variable.
Ensure valid list of context type var decls is passed to
instantiateScheme macro.
The code in MethodCall needs to be fixed in order to respect
context type variables in case of instantiation of a non-static inner class.
Contract stems from the fact that constraint args influence Rules hashes (unique tags)
and so must be stable under irrelevant changes for incremental logic
Refactor whe way TypecheckingResultsCache is updated:
all mutatiting methods extracted to Update subclass, which is
only available to the updater.
Make TypecheckingState a regular container for (unit) caches.
Make TypecheckingService responsible for managing caches.
Extract TypeModuleOwner and TypeModelHandler classes.
Get rid of QueryResultsCache, merge into TypecheckingResultsCache.
TypeModuleOwner to manage "repository" cache.
Now whether unchecked conversion is allowed is controlled
by ConvertsContext.Options of convertsTo relation.
Introduce 'erased()' term to be used in raw type params.
Drop 'uncheckedConversion' parameter in all macros.
Classifier kind:"raw" is now used only for Recover.
Allow unchecked conversions by default. Forbid for sequences.
Can't properly handle this case now.
To handle this case of no type of initializer in assignment context
need to discern cause of this "no type". If it's because of error --
then can't assign to it any type. If there were no error
(e.g. case of test) -- then type can be inferred from assignment ctx.
Anyway it's not very important corner case, can leave this test relaxed.
Matching on two constraints without an "anchor" (origin)
is essentialy quadratic. On a large root there may be
many typeof/expectType instances and it slows down the
computation considerably.
