From @FROGGS

Fixed by jnthn​:
FROGGS m​: sub foo(int $x) { $x }; foo(Int)
camelia rakudo-moar a49900​: OUTPUT«Cannot unbox a type object␤ in sub foo at /tmp/HhxDcb2kX0​:1␤ in block <unit> at /tmp/HhxDcb2kX0​:1␤␤»

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

From @usev6

I added a test for the 'sub(int $x) ...' example to S06-signature/types.t with commit Raku/roast@cae9192292. Please note that I had to expand the body of the sub a litte bit -- otherwise the command didn't die on rakudo.jvm​:

$ perl6-j -e 'sub foo(int $x) {

$x }; foo(Int)'; echo $

$ perl6-j -e 'sub foo(int $x) { say $x }; foo(Int)'
Cannot unbox a type object
  in sub foo at -e​:1
  in block <unit> at -e​:1

But more importantly, the simple case without any sub involved gives a segfault on rakudo.moar nowadays​:

$ perl6-m -e 'my int $x = Int'
Segmentation fault

$ perl6-j -e 'my int $x = Int'
Cannot unbox a type object
  in block <unit> at -e​:1

$ perl6-m --version
This is perl6 version 2015.02-252-ge395707 built on MoarVM version 2015.02-45-g86cb4db

Fixed this case, and added a tests (also covering num and str) in S02-types/native.t.
