Subject: Ruby 1.9 Binding#exec and introspection

I'd like to open up a discussion about extending the Binding class we
have available in Ruby. Apologies if this is already happening somewhere
but I couldn't find any discussions on the topic.

I think it's great Ruby 1.9 now has added Binding#eval. Having access to
the local binding is a powerful tool and it would be great to see it
become more accessible.

I think it would be nice to see something like the new class_exec and
instance_exec methods for the Binding class so we don't have to go
through string evals. Specifically a Binding#exec

Some introspective abilities would also be a bonus. The most obvious
ones I can think of are: Binding#local_variables,
Binding#local_variable_get

There's probably more information we can pull out of the local binding
but these two are things I really miss from Python.

What do you guys think, let's hear some ideas.

Cheers
