I have a vim mapping for that kind of thing. Since it's not trivial to get the variable name with perl standard functions I consider that a good workaround to let your editor help you.
imap DUMPER <ESC>^iwarn __PACKAGE__.':'.__LINE__.$".Data::Dumper->Dump
+([\<ESC>llyw$a], ['<ESC>pa']);<ESC>

this mapping lets you type
$my_variableDUMPER
which gets expanded to
warn __PACKAGE__.':'.__LINE__.$".Data::Dumper->Dump([\$my_variable], ['my_variable']);

I can only say that I'm using this for many years now and it has saved me so much time, when typing, as well as when trying to find out the source of Dumper statements in the log. (ever worked on team code and getting various $VAR dumps in the log not knowing where they come from?)
