Re^2: What is correct way to reference?

local $" = "\n"; # change list separator to a newline

say ( ref $_ eq "ARRAY" ? "@$_" : $_ ) for ( $foo, $baz );

Wouldn't it be easier/quicker/clearer/more informative to use something like Data::Dumper::Dumper() (which is core) or Data::Dump::dd() (not core, but I like it a lot) to dump a scalar or reference and see exactly what its value or structure is? Why go through such specialized acrobatics?

Yes, of course! This is a completely contrived exercise to show $" ... simply for edification. The way forward always starts with a minimal test.	[reply]
