__init__(self, vars=(), parent=None)
Create a new context.

set(self, name, value)
Set the variable with this name.

__setitem__(self, name, value)
Set the variable with this name.

get(self, name)
Lookup the variable with this name.

__getitem__(self, name)
Lookup the variable with this name.

iter(self)
Iterate over all variables defined in this context.

__iter__(self)
Iterate over all variables defined in this context.

__repr__(self)
