I've just started thinking about generics in my Ruby <=3D> CLR bridge. This=
is
what I'd love to be able to do:

channel =3D ChannelFactory<IOutputChannel>("
http://www.flickr.com/services/soap/").CreateChannel

The problem is how to deal with the stuff in angle brackets since < and >
are not legal inside of Ruby constants. Any thoughts on how to syntacticall=
y
deal with this issue?

Thanks

Whoops, that should be:

channel =3D ChannelFactory<IOutputChannel>("
http://www.flickr.com/services/soap/").new.CreateChannel<http://www.flickr.=
com/services/soap/%22%29.CreateChannel>

it is legal (just use another symbol construction literal):

x = :"< ... >"
p x

I think constant names with < and > would be so hard to read for
humans that Ruby is right to make them impossible

How would you (or Ruby) interpret:

class A
end

class B<A
end

or:

puts "Yes" if Object>String

?

(You can take that as a rhetorical question

Maybe you should use nested constants (using :.

Thanks David, I wasn't really thinking about those corner cases at all
(reveals the tunnel vision that I have right now).

Are there *any* characters that I can use in Ruby to escape the type
information in the constant name?

Thanks
