dup is used to copy the contents of an object, but not necessarily all
its internal attributes. You can think of dup as a kind of copy
contructor.
clone on the other hand tries to copy internal state as well.
For example:
a = "hello" # => "hello"
a.freeze # => "hello"
b = a.dup # => "hello"
b.frozen? # => false
c = a.clone # => "hello"
c.frozen? # => true

Eval seems reasonable. If you _know_ that the name is a class, you
could also use Object.const_get(string)
Object.const_get("Array") # => Array

You'll need to remember to remove the file names from $" if you're
using require. You can also get the file name from set_trace_func it
you can find a safe method to call.

My guess is it would depend on the class. If a class sets global
state, then it might be tricky.

You could hook Module.remove_method and .undef_method.
I'd personally like to see more browser support in 1.7, which is why I
started the browser thread earlier. Your experiments are leading the
way to defining stuff that we might like (particularly if you start
working on compile and go and incremental compilation ;-)
