# This represents the method at source code level (sis vool)

# Type objects are already created for args and locals, but the main attribute

# is the source, which is a Vool::Statement

# Classes store VoolMethods, while Types store TypedMethod
|
|
# A Type referes to a Class , but a Class (interface) is implemented by many types
|
|
# as it changes during the course of it's life. Types do not change. Objects have
|
|
# type, and so only indirectly a class.
