22:57 bbkr: r-m: use A B; # LTA error
22:57 camelia: rakudo-moar d78c67: OUTPUT«===SORRY!===␤Cannot invoke null 
object␤»

STD behavior:
22:54 bbkr: std: use A B;
22:54 camelia: std f9b7f55: OUTPUT«===SORRY!===␤Cannot locate 
module A at /tmp/y5X2aKRpWl line 1:␤------> use A 
B⏏;␤Undeclared name:␤     'B' used at line 1␤Check failed␤FAILED 
00:00 134m␤»

STD response also seems weird to me - why it did not stop after "Cannot locate 
module A" fatal error but reached "Undeclared name: B" check?
