One could write a nice subroutine useful in debugging, whic when called in the following way: `my $aLex=25; print(display($aLex),"\n");` [download] would print `$aLex == 25` [download] -- Ronald Fischer <ynnor@mm.st>	[reply] [d/l] [select]

Try Data::Dumper::Simple or Data::Dumper::Names which do this.	[reply]

I'm not so happy with either one. Data::Dumper::Simple uses a source filter, and source filtering has already bitten me more than once. Data::Dumper::Names uses undocumented features in Perl which doesn't make it trustworthy either... -- Ronald Fischer <ynnor@mm.st>	[reply] [d/l]

Encapsulation rules? Which ones did s/he break? Looks like a solid debug example to me.	[reply]
