Would it be possible to assign it as a reference and change the
reference on the first write (similar to copy-on-write)? In that case
I'd suggest doing something similar to:

* Assign all variables to their provided name
* Assign a reference as the "cleaned" version of their name if there
isn't already an existing version of the clean name in the map

Quite a few services use "." in their query string variables (such as
Solr, for one), and the  mangling of the query string names requires
you to parse the query string yourself if you want to write a front
end service accepting the same kind of API.
