When property initializer of some inner entity (e.g. anonymous object) contains
a reference to some outer entity (say, a property of the outer class), we need
to make sure we called "lookupInContext" on this entity's owner class, so that
"setCaptureThis" was called on the appropriate closure
#KT-4176 Fixed
KT-4106: VerifyError: Can't access outer this in a lambda in inner class' constructor
KT-3152: VerifyError when accessing from a function of object to a field of outer outer class
#KT-3523 Fixed
#KT-4106 Fixed
#KT-3152 Fixed
Superclass of closures should now be FunctionImplN instead of FunctionN. Since
these -Impl classes are needed only in JVM, the corresponding descriptors and
types are created in the back-end only.
