S09​:1043 says that junctions passed as components of a slurpy
array or hash do not cause autothreading, but Rakudo currently
autothreads junctions over slurpies on some multisubs​:

  $ cat x
  multi sub foo(*@​a) { say 'foo'; }
  multi sub bar(Any *@​a) { say 'bar'; }
 
  foo(1|2|3);
  bar(1|2|3);

  $ ./perl6 x
  foo
  bar
  bar
  bar
  $

As of 91408af, the call to foo() is correct.

The call to bar() should either execute once, or fail outright
(because a Junction argument isn't of type Any).

Tests for this are being added to S06-signature/slurpy-params.t .

Now gives​:

Assigned to moritz++ for tests to be reviewed/enabled.
