I understand the above use, but...

...this suggestion is not viable when the reason for the periods
is to map to nested data, and underscores '_' are already in use
in simple multi-word names.

The point is that we should be able to use any normally legal
(for CGI programming) request parameter names and be able to
retrieve their values without data-structure-walking gymnastics.

If the framework *also* wants to categorize the request parameters
(making a tree-shaped data structure like it does now) it should
be free to do so...but should not break the traditional CGI-style
programs in the process.

Use two different variables to get at the differently organizations
of the parameters, just picking names out of the air for example:

...and since ruby has references (multiple variable names can refer
to the same data,) this would _not_ have to double the memory use
for storing the request parameter data.

Agreed, the nested version does need more nesting.
