From @BenGoldberg1

On #perl6 IRC, I typed this​:

<BenGoldberg> m​: my \foo = Callable but role :​: { };
<+camelia> rakudo-moar ef9872​: OUTPUT​: «X​::Method​::NotFound exception produced no message␤ in block <unit> at <tmp> line 1␤␤»

If, at my command prompt, I type perl6 –e “my \foo = Callable but role :​: { };”
I get instead​:

No such method 'mixin' for invocant of type 'Perl6​::Metamodel​::ParametricRoleGroupHOW'
  in block <unit> at -e line 1

Including, oddly, an extra blank line after the error and before my prompt.

Please provide the version of rakudo you're running locally so we can rule out any version skew.

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

From 1parrota@gmail.com

As a kibitzer, I tried that with "This is Rakudo version 2017.04.3
built on MoarVM version 2017.04-53-g66c6dda
implementing Perl 6.c".
and got​:

perl6 –e "my \foo = Callable but role​:: { };"
Could not open –e. Failed to stat file​: no such file or directory

while​:
perl6 -e "say 'boo'"
boo

worked just fine, as you can see.

I just noticed the - was a different length, so I changed it, et voila​:
perl6 -e "my \foo = Callable but role​:: { };"
===SORRY!=== Error while compiling -e
Undeclared routine​:
  role used at line 1. Did you mean 'roll'?

Something bit you; note that you are not using "-e" but "–e" (U+2013 EN
DASH).

Right, the consequence of cutting & pasting. It's interesting that the
error message on the corrected version is unlike either of the
original examples.

C​:\Users\Ben (user)>perl6 -v
This is Rakudo version 2017.01 built on MoarVM version 2017.01

This was a temporary change​:

23​:42 <+committable6> [Coke], ¦2017.01​: «No such method 'mixin' for invocant of

Note that 2017.01, 2017.05 and f0c3fb all give the same output.

Checking the specific version you reported earlier, I see the difference.
