There are a whole lot of fun things we could do with special associative
array paramters. Examples:
An AA named "functions" that looks up values in the shell function hash
table. `functions foo` would be the same as `print $functions[foo]`. The
"functions" AA could be read-only, but perhaps it would be fun to be able
to edit the function with `noglob vared functions[foo]`?
How about an special AA named "files"? "$files[foo]" would be equivalent
to "$(<foo)". One step further: `noglob vared files[foo]` replaces `zed`
almost entirely (except for the ZLE rebinding bits). OK, maybe that one
is getting a little carried away ... but if the OS supports mmap() ...
Hmm; if only there were a way to cause a module to autoload upon reference
to a parameter that it defines ...

And, of course, the Perl mapping to db files (presuming that configure
notices some compatible db library).
