This would be the way to go.  Alternatively, you could create these
blocks as _ss or _ii, and work on packed data.  Depending on where in
your flowgraph you need this operation, this would be much faster.
See:

http://gnuradio.org/trac/browser/gnuradio/trunk/gr-gpio/src/lib/gpio_and_const_ss.cc

...for an example of a block that logically ANDs a stream of short
integers with a constant value.
