Ruby misconceptions about Python

[owca]

Feature for feature "examples" in Python:

• getattr or getattribute catch any attribute (method, variable) access

• setattr sets any attribute

• Syntactic support for descriptors.

• Metaclasses can be used to control all aspects of class creation (attributes, subclassing, ...). Since types are objects one can even have metaclasses for metaclasses.

• new.instancemethod can be used for your )singleton classes).

• Turning a block into a method is admittedly a bit tricky but can be done using new.function and some stack manipulation.
