This is using a soft, or symbolic, reference. Avoid using them. perldoc
perlref explains:
[Symbolic References are] powerful, and slightly dangerous, in that it's
possible to intend (with the utmost sincerity) to use a hard reference, and
accidentally use a symbolic reference instead. To protect against that, you can say
use strict 'refs';
