Can't use Method::Signatures::Modifiers with parameterized roles

[bitbugprime]

X.pm:

use MooseX::Declare;

role X (Str :$role) {
has "x_$role" => (
    is       => 'ro',
    isa      => 'Str',
    lazy     => 1,
    default  => sub { 'junk' },
    init_arg => undef,
);

method "print_x_$role" () {
    my $c = $role;
    print $c, "\n";
}
}

1;

main:

use MooseX::Declare;
use Method::Signatures::Modifiers;

class Z {
with 'X' => {role => 'test'};

method roller { '' }
}

my $a = Z->new;
$a->print_x_test;

If you comment out "use Method::Signatures::Modifiers" and run "perl main", it works fine. If you run as is, you get:

"my" variable $role masks earlier declaration in same scope at X.pm line 13.
"my" variable $c masks earlier declaration in same statement at X.pm line 14.
Type of arg 1 to X::method must be block or sub {} (not string) at X.pm line 12, near ""print_x_$role" ("
syntax error at X.pm line 12, near ""print_x_$role" ("

Turning on debugging...

Somehow Method::Signatures::Modifiers is getting involved with the compilation of method "print_x_$role". Seems like that should be out of its scope!
