I goofed.  I was trying to give an example of what to do to keep from  
changing defaultFolder so it would be OK when an external is loaded.   
I worded the 'throw' above as if the external was loaded in the "...  
blah blah blah ...".

The last line is better like this:

if bad then throw "Error while defaultFolder was changed."

Or whatever is appropriate for the particular situation.

All the more why 'catch' should be optional.
