Case insensitive version of string.Template?

Gabriel,

If you can guarantee the identifiers are all lowercase inside the  
dictionary:

class lowercase_dict(dict):
     def __getitem__(self, name):
         return dict.__getitem__(self, name.lower())

import string
values = lowercase_dict( name='John Doe', phone='999-555-1212' )
output = string.Template( 'My name is $NAME and my phone is $Phone.'  
).safe_substitute( values )
</snipped>

Brilliant!! Using a custom dictionary solves my problem and gives me
some ideas on similar challenges.

Thank you!
