You can reduce the amount of syntax in the line you provided and it doesn't even require the use of an additional module. The expression $ref->{'foo'}{$bar} is exactly equivalent to $ref->{foo}{$bar} and the latter has the advantage that you don't waste any time pondering why the author has chosen to enclose foo in single quotes like that.
