When I'm looking at the [CallEvent ](https://clang.llvm.org/doxygen/classclang_1_1ento_1_1CallEvent.html) inheritance graph, there could be a couple other options too. Don't get me wrong, the `SimpleFunctionCall::getRuntimeDefinition` looks like the right place. I'm just curious.

As far as i know, `__invoke` will always be a normal static member method for lambda, and static member method will be modeled as `SimpleFunctionCall` in analyzer, other derived classes of same level seems to   for memory-allocation related (`CXXAllocatorCall`, `CXXDeallocatorCall`), or class-instance related (`AnyCXXConstructorCall`, `CXXInstanceCall`)
