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

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]

I agree that there are uses for a subroutine that can return such names as requested, but usually when people ask for something like this, its a sign of a more mundane problem solved in the wrong way.	[reply]

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

hkwilliamson hasn't revealed what (s)he is going to use this introspection sub for. The debugging example was written by ysth.	[reply]
