1707549: Remove Perl 5.24+ syntax restriction
Quoth the Perl docs: "An experimental feature added in Perl 5.14 allowed each,
keys, push, pop, shift, splice, unshift, and values to be called with a scalar
argument. This experiment is considered unsuccessful, and has been removed.
The postderef feature may meet your needs better."
The specific instance here was probably just a typo or thinko the did the
right thing on Perls "of a certain age" ... so, we fix that here, now.
