OOOOH! My complements....
The problem is not really with the Getopt::Long,
but with the need to be more sensitive to
a) perldoc perlsub
- cf the prototyping problem here
- note the warning if the "&" is removed
b) perldoc perldata and perldoc -f split
since what is being passed is a string, and should
be converted by any means neccesary into an array
GOOD use of the 'local' since we are dealing with a
'reserved token'....
