lol. that's a *first* for me on c.l.r.! well - ts hasn't responded so

how about marshaling? if you dynamically alias methods - can you marshal
that?

but perhaps less safe. the reason i have all the classes and interface defs
as private is that, only the class designer should, really, know which
different interfaces are possible and what constraints there are (eg. once
you use interface 'x' the object may not ever be used via interface 'y' -
these situation are not that hard to imagine...) maybe this is just the evil
c++ side of me coming out?

i see that. however, my idea was simply to separate data from methods, and to
let the methods be 'assign-able'. eg. to switch interfaces. kind of funny
that oo programming talks about putting data and methods together and here we
go separating them... ;-) i guess i'm thinking that, although it is certainly
possible to separate methods from data (as i did) there is still a potentailly
*very* tight coupling between the two - thus the private inner class thing...

in my code, all that would be needed to do this is an
attr :interface
in other words, you can do this if the interface class is publicly available:
class << k.interface
def foo; 'foo'; end
end
you get the idea...

i wouldn't agree here, although it would make the code longer than 51 lines
one could easily design
class Klass
def Klass.register_interface interface
unless @trust
raise unless has_right_methods interface
raise unless passes_unit_test interface
raise unless some_constraint_or_another interface
raise unless etc interface
end
end
end
...
Klass.register_interface MyInterface

i, for one, like the idea alot. yours may be alot better - i'm just
brainstorming...
