The way the documentation was written I thought that throw is an
exported subroutine, whereas in reality the example meant
DBException->throw(whatever). Indirect invocation sucks :) By the way,
since I throw the exception above as plain text (not as hashref with
-text => xxxx), I need to inherit from Error::Simple.
This raises another question though - I thought in order to have a class
I *must* declare a package. However you get away by simply initiating a
variable. Does autovivification work for packages just like it does for
hash keys?
Thanks!
