BSH can "import" any packages it wants - see some of the BSH scripts
in extras and bin.

Now sure about browsing JMeter packages. The BSH documentation might
give some clues.

I'd assumed that any variables that were needed could be passed in as
parameters to the script - or embedded in it, if using the script
panel (rather than using a file name. JMeter variables embedded in
files are not interpreted, as the file is passed directly to BSH).

However one could import the appropriate JMeter packages and define a
shortcut method to access them.  See for example extras/startup.bsh.

If this was found to be generally useful, get and set methods could be
provided by the classes that instantiate the interpreter, in much the
same way that access to responseData etc is currently provided.

Well, there's the BSH documentation, some BSH scripts in bin and
extras, and there's always the JMeter Wiki if you want to add some
details to it!
