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?

STD *is* wrong to report both, but the correct thing to complain about is the undeclared name B. That is the argument to the use operation, and so is evaluated before the module search. Rakudo now does this​:

$ perl6-m -e "use A B;"
===SORRY!=== Error while compiling -e
Undeclared name​:
  B used at line 1

Test added in S32-exceptions/misc.t; resolving.

The RT System itself - Status changed from 'new' to 'open'

@jnthn - Status changed from 'open' to 'resolved'
