The "is" option is basically a kind of macro for the "accessor" and  
"reader" options from Class::MOP's attributes.

This:

has 'foo' => (is => 'rw');

ends up "expanding" into this:

has 'foo' => (accessor => 'foo');

and this:

has 'bar' => (is => 'ro');

ends up "expanding" into this:

has 'bar' => (reader => 'bar');

Of course you can manually set these things in Moose as well, like so:

has 'foo' => (
     reader => 'getFoo',
     writer => 'setFoo',
);

So, while you are only seeing generate_accessor_method() called, I  
would keep generate_writer_method() around for completeness because  
you might need it at some point.
