You can use the irb command inside irb:

irb(main):001:0> module M; X=1; end
=> 1
irb(main):002:0> irb M
irb#1(M):001:0> X
=> 1

This puts you in a context where the object you've irb'd is self. (Use
'exit' to get back to your top-level irb session.) You could also
include the module, or reopen it. There are some differences among
these techniques, but somewhere in there you can probably find
something.
