Closable with tests?

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

From @usev6

This fails now with X​::AdHoc​:

for my $/ ();
===SORRY!===
Missing block
at <unknown file>​:1
------> for my $/ ()⏏;
  expecting any of​:
  scoped declarator
  constraint
  postfix
  parameterized block
Other potential difficulties​:
  Redeclaration of symbol $/
  at <unknown file>​:1
  ------> for my $/ ()⏏;

If I add an empty block it doesn't die (but warns for the Redeclaration of symbol $/).

Since there is a NYI spec change in S05 ("In order to detect accidental use of Perl 5's unrelated $/ variable, Perl 6's $/ variable may not be assigned to directly.") the current behaviour will probably change.

The output has changed​:

22​:59 <jdv79> m​: for my $/ ();
22​:59 <camelia> rakudo-moar 8e8936​: OUTPUT«===SORRY!=== Error while compiling /tmp/kebuZ3fC7m␤Signatures as constraints on variables not yet implemented. Sorry. ␤at
  /tmp/kebuZ3fC7m​:1␤------> for my $/ ()⏏;␤»

From @jdv

No tests needed here as the issue is resolved and the new
error message is linked to "post constraints" which I'm
guessing is what is being conjectured about here​:
http://design.perl6.org/S12.html#Multiple_constraints.

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