It seems like a syntax error to me - you got your brackets & parenthesises out of sequence:

if [[ $state != ?? || $state != +([A-Z)] ]]
and
if [[ $city < ??? || $city != +([A-Z)] ]]

Then again, I never understood the difference between a single bracket and a double bracket. But that sequence syntax thing jumped out at me...

ppi::statement::unknown

PPI::Statement::Unknown(3pm)				User Contributed Perl Documentation			      PPI::Statement::Unknown(3pm)

NAME

       PPI::Statement::Unknown - An unknown or transient statement

INHERITANCE

	 PPI::Statement::Unknown
	 isa PPI::Statement
	     isa PPI::Node
		 isa PPI::Element

DESCRIPTION

       The "PPI::Statement::Unknown" class is used primarily during the lexing process to hold elements that are known to be statement, but for
       which the exact "type" of statement is as yet unknown, and requires further tokens in order to resolve the correct type.

       They should not exist in a fully parse valid document, and if any exists they indicate either a problem in Document, or possibly (by
       allowing it to get through unresolved) a bug in PPI::Lexer.

METHODS

       "PPI::Statement::Unknown" has no additional methods beyond the default ones provided by PPI::Statement, PPI::Node and PPI::Element.

SUPPORT

       See the support section in the main module.
