Example​:

  sub f (*%args) {
  say .perl for %args.keys
  }
 
  my %typedhash := :{ a => 1, b => 2 };
 
  f |%typedhash;

Ouput​:

  "Str|a"
  "Str|b"

Expected output​:

  "a"
  "b"

This bug is still present in

Rakudo version 2017.08-8-g753c9a5ea built on MoarVM version 2017.08.1-19-g151a2563
implementing Perl 6.c.

Shorter test-case​:

  ➜ say :{ a => 1, b => 2 }.FLATTENABLE_HASH;
  {Str|a => a => 1, Str|b => b => 2}

Compare to a normal Hash which works fine​:

  ➜ say { a => 1, b => 2 }.FLATTENABLE_HASH;
  {a => 1, b => 2}
