RFC: Add Logical Shifts for bitwise string operations

That's a very good point. However it would be discernible by the
context. If there's a literal or a variable to the left of the
operator, it'd be the shift operator (since any literal or variable
the left of the heredoc would result in a syntax error). But it
should likely be more concrete. Perhaps b<< or something else.

I'll update the RFC to leave the selection of an operator pair up for
discussion.

Thanks,

Hello all,

I have added an RFC for the addition of logical bitwise shift
operators.  (>>> and <<< proposed).

Feedback welcome,

Your RFC should probably address the issue that we already have a <<<
operator. See http://php.net/heredoc
