     * Important notice!
     *
     * This is the type checker of *owner* module, i.e. the module which has declared the class.
     *
     * In MPP, we have different "views" on the one and the same class. I.e. if we have a common 'class Foo : Expect',
     * and on JVM we have 'actual typealias Expect = CharSequence', then from "common view" Foo isn't assigneable to CharSequence,
     * while from the "JVM view" it is.
     *
     * LazyClassContext is usually shared across all such views, so be careful - using this typechecker in "platform views" is not correct.
     * Relevant entities usually have a separate instance of KotlinTypeChecker/KotlinTypeRefiner, see for example
     * [org.jetbrains.kotlin.resolve.lazy.descriptors.LazyClassMemberScope].
     *
     * See also KT-44898 for example of issues which might happen if the wrong typechecker is used in "platform view".
