UseVariableTypeForInitialResolution

BOOL

Special value signalling that the typedesc VariableType should be used for resolving the initial node. This is probably only relevant when using GetSymbolicSubNode. One usecase of this is the resolution of nested arrays eg. …structCmp[0][1] as then the last node is the one of the structCmp but we need to resolve starting from the left hand array.
