Surely using positional parameters causes serious braindamage :-)

A solution could be using named parameters (a hash, I mean). For example, parameters for ClickInterval and Exposure could be respectively:

%param = ( firstClick => 12345, secondClick => 21345) ;

and

%param = ( 'value' => 911 ) ; # call for help on "Exposure"
[download]

Once you compose the %param hash someway, you could end up your code with a simple call:

my @res = $function_etc_etc{$a_function}->(%params) ;
[download]

and each sub will get only the parameters it deserves :-)
