mod_dtcl must parse QUERY_STRING to find the right variable;
every time you call [vars get xxx], the module (in the worst case)
must parse every variable in the string - which is exactly what
you wanted to avoid.
I think this approach is effective only if you access
'very few' out of 'a lot of' variables. We should consider the case, anyway.

Too complex, I think. The result could be even slower than duplicating values
(a lot of tests involved, both in mod_dtcl and in the scripts).
