A subroutine reference may now be suffixed with an arrow and a (possibly empty) parameter list. This syntax denotes a call of the referenced subroutine, with the given parameters (if any).

This new syntax follows the pattern of $hashref->{FOO} and $aryref->[$foo]: You may now write &$subref($foo) as $subref->($foo). All of these arrow terms may be chained; thus, &{$table->{FOO}}($bar) may now be written $table->{FOO}->($bar).
