"perldoc perlref" addresses the nested subroutine problem, and
suggests using something like this:
local *printQueryParams = sub {
instead of this:
sub printQueryParams {
The assignment to the typeglob is pretty slick in that it let's you
call the anonymous subroutine as if it were a subroutine named
printQueryParams.

I thought the whole philosophy behind Perl is that it does what you
expect it to do and this is in no way what anyone would expect it to
behave!
Thanks for the link. I guess I'll read up on this guide more
carefully
before I ask any further questions.
