The following error is a regression in Perl 5.28.
No assignment to the "my" variable $m, but correct
assignment to $t.

my $m = 'TEST_my';
$t = 'TEST___';
$k = 'k';
($m = '??'.$k) .= ' m';
($t = '??'.$k) .= ' t';
print $m,"\n",$t,"\n";

output for Perl 5.26.2.1 (correct)

??k m
??k t

output for Perl 5.28.0.1 (no assignment in line 4 to $m)

TEST_my
??k t
