Dictionary, keys and alias

[Glauco]

I want to insert a concept of alias in a dict_based class.

The idea  is to have a facoltative name in the same dict that correspond 
at the same value. With this alias i can change original value.

example:

mydict['a'] = 1
I must define an alias  example: myFunctAlias( mydict, 'a', 'b')
print mydict
{'a':1, 'b':1}
mydict['b'] = 2
print mydict
{'a':2, 'b':2}


The only idea i have is to implement two dictionary one for convert 
name, alias in two keys with the same value (eg.numeric) in the first 
dict. The second for store only one time the k, v .


Any suggestion ?
