ReadonlyfunctionTypes: ReadonlySet<RType>A set of all types of function-related nodes in the normalized AST, i.e. function definitions, function calls, parameters, and arguments.
Type guard for RFunctions nodes, i.e. checks whether a node is a function definition, function call, parameter or argument.
If you need the specific type, please either use the respective type guards (e.g., RFunctionDefinition.is) or check the type node directly.
