In that case, you should catch subinstances of Exception. An Exception is 
not an Error, it won't raise a debugger. Actually it will do nothing by 
default.
IMHO you should catch what needs to be cached:
 	Error, Abort, UnhandledError, Halt

It is an exception. You "throw" it, and when it's resumed, it'll contain 
read-only source files.

Make a new PLV variable which implements the same API, then rewrite the 
users. It takes effort, because it must work while it's being used.
