I don't know if it's the most elegant, but if you wish to have multiple keys 
map to a value then you can resort to a tuple containing both keys as your 
map's key.

That approach is very common.  For example, with the "dictionary of keys" 
matrix data structure, the matrix elements are stored in a key:value pair 
whose key is a (row, column) tuple.


Hope this helps,
