Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(symbol, *args, &block) ⇒ Object

this is actually def value, but it mustn’t override the value methods for the literal nodes.

Instance Method Details

#parenthesised_value ⇒ Object

this will end up being called for anything that’s not handled by one of the XXXLiteralNode modules. Right now it basically applies to function calls only.
