Hi,

I am new to the PHP internals, and I was just looking through the code
related to parsing break/continue statements. It looks that as of PHP
5.4, Zend/zend_language_parser.y accepts both "T_BREAK expr" and
"T_CONTINUE expr" and check to make sure "expr" is a positive integer
in the function zend_do_brk_cont. Doesn't it make more sense to
replace "T_BREAK expr" with  "T_BREAK <positive integer>" (the same
goes for the continue statement)?

Thanks in advance!
