This is untrue. In fact, Perl supports the trailing comma because C and
pretty much all C-based languages (like javascript, java) support it.
The trailing comma is a must in long enumerations (one per line) if one
wants to get a clean diff output. Like in the Shlomi's modified example:

my %person = (
	first_name  => 'Yosi',
	last_name   => 'Steinberg',
	phone       => '1-800-800-800',
	# ...
);

Regards,
Mikhael.
