in reply to Deparse the switch
Here is the translation of the answer of Rafael Garcia-Suarez on mailing-list 'paris-pm-list@pm.org' :
Deparse module included in version 5.6.1 cannot do that.
Deparse of version 5.8.0 will understand switches -i, -l, -w and -0 (but probably only with perl5.8.0 interpreter).
