JBuilder Professional allows you to create standing expressions that are
evaluated at every breakpoint (I'm not sure about the free version). This
is sloppy and stupid, because many of those expressions will be
non-sensical inside most scopes! In those cases, JBuilder just says the
expressions are undefined. Also, it's cumbersome to add in new
expressions. They are dancing around the right answer, which is clear to
us because we have a repl built into the IDE.
