I will look into isolate, though the problem I face isn't due to
production/professional environments.

I often evaluate different gems or run through example code as part of
course work or general curiosity.
Sometimes I settle on a solution that I take further on, and its usually at
that stage that I need to figure
out exact gem dependencies. I often end up being shanghaied into helping out
someone else's ruby
problem as well. The messiest issues are always gem related.

I was just curious if there was a mechanism to inspect the loaded gems from
an application (and their
versions). Even unusual techniques, like perhaps objectspace inspection, or
reopening gem specific
methods.

Just curious if anyone knew any techniques.
