The TOPLEVEL_BINDING constant...but the standard disclaimer is don't
use eval (depends on what you're doing though). It is generally not
safe unless you have 100% control over the input, because it can do
everything ruby can (i.e., eval doesn't run in any kind of sandbox),
so in an untrusted context, it's dangerous.
