I don't know if it's possible, but the best way would be to create a 
different "==" for each part:

- URI userinfo part:  $ru == "aliCE"
  - Case sensitive
  - Allows hexadecimal escaping ("aliCE"  ==
   "%61aliCE  !=  "aliCE")

- URI protocol and domain:  $rp == "sip", $rd == "domain.org"
  - Case insensitive

- URI parameters/headers:
  - Case insensitive
  - Allows hexadecimal escaping in key and value (";tag=aliCE"  ==
   "T%61G=%61aliCE )

- Complete URI:  $uri == "sip:user at domain"
  Is it possible to compare each part of the URI as above?

I think this is perfect since all the SIP grammarm, except URI username and 
method names (INVITE, BYE...), are case insensitive (header name, header 
value...).

AFAIK the meaning of "===" operator changes in each language.
