Wonderful! - I always hated the 2 issues with Data::Dumper - it wants a REFERENCE, and it wont easily tell you the variable NAME.
There was one additional nit - which perhaps you can pick -the need to say "print Dumper (\$blah)" - why keep repeating the "print" or "warn" .. wouldn't is be nice to have an OO interface that remembers what you want to do .. something like:
my $Dump => new Data::Dumper::Simple(
Output=>"warn", # or "print"
# or: Output=\&CodeRef
$Dump->() ; # Can't think of appropriate syntax here..
# Line above would do the equivalent of
print Dumper ($$this,%that,@other);
# If we no longer want to output %that, do
# or even
Earth first! (We'll rob the other planets later)
