Functions

func IsModuleCall

func IsModuleCall(node Node) bool

IsModuleCall returns true if the expression node is a module call, e.g. pe.entry_point

func IsPrimitive

func IsPrimitive(node Node) bool

IsPrimitive returns true if the node is a primitive value like an Integer, Float, String, Variable, or Bool
