Example patterns for using the :class:`ChainMap` class to simulate nested
contexts::
c = ChainMap() Create root context
d = c.new_child() Create nested child context
e = c.new_child() Child of c, independent from d
e.maps[0] Current context dictionary -- like Python's locals()
e.maps[-1] Root context -- like Python's globals()
e.parents Enclosing context chain -- like Python's nonlocals
c = ChainMap() # Create root context
d = c.new_child() # Create nested child context
e = c.new_child() # Child of c, independent from d
e.maps[0] # Current context dictionary -- like Python's locals()
e.maps[-1] # Root context -- like Python's globals()
e.parents # Enclosing context chain -- like Python's nonlocals
d['x'] Get first key in the chain of contexts
d['x'] = 1 Set value in current context
del['x'] Delete from current context
list(d) All nested values
k in d Check all nested values
len(d) Number of nested values
d.items() All nested items
dict(d) Flatten into a regular dictionary
d['x'] # Get first key in the chain of contexts
d['x'] = 1 # Set value in current context
del['x'] # Delete from current context
list(d) # All nested values
k in d # Check all nested values
len(d) # Number of nested values
d.items() # All nested items
dict(d) # Flatten into a regular dictionary
