No pardon required. :)

I think you have a minor typo:

class Bar
use Mod_B, :include => [:meth_b, :meth_c] # include only 'meth_a'
and 'meth_b'
use Mod_B, :exclude => :meth_c # same net result as
above
end

Shouldn't that be :exclude => :meth_a instead, to get the same net
result?

It should be ":include => [:meth_a, :meth_b]"
