I don't really see how this is related to the in operator, other than 
that some languages reuse the same keyword for both purposes.

My immediate association when I saw this proposal was not "ah, like the 
loop syntax in JavaScript", but "ah, like the IN() operator in SQL".

Given the ability to write foreach ( $foo as $key => $value ), I'm not 
sure adding a variant syntax of for ( $key in $foo ) has that much value 
for PHP.
