CGI->param. There is no reason to duplicate CGI module.

Validation and accessing. Parsing via CGI->param.

There is another reason I want to move accessing and validation of
parameters to the "action" function (perhaps, as you suggested, via
"wrapper" function), namely removing some global variables. Perhaps it is
unnecessary, but I wonder how well that works with mod_perl. Other global
variables are configuration and do not change form execution to execution
of script...
