Why and how can I avoid that.
(yes, i know about printf)
So use it ;-) Read the section "Auto-increment and Auto-decrement" in
" perldoc perlop " which ends with the phrase
The auto-decrement operator is not magical.
Unlike ++, which keeps the string-ish nature of the variable contents,
the -- operator turns the string into a number and simply does a
numerical decrement with it. So if you need this four digit format and
a decrement, you'll have to use printf (or sprintf).
