You needn't test for whether $ENV{QUERY_STRING} is defined or not, because undefined things automatically have zero length.

"CGI.pm then would generate a parameter "keywords=Test", and we would remove that parameter accordingly. But that would be only the half of the way: I think that "Test" in that case should be a KEY in the parameter list which has an empty (or undefined) value."

Then you could try something like:

for ($ENV{QUERY_STRING}) { $cgi->{param}{delete $cgi->{param}{keywords}} = "" if length && !/[&=]/; }
perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
