Hi monks, this code...

package MyParseExcel;
use Spreadsheet::ParseExcel;
use Moo::Role;
use MooX::Types::MooseLike::Base qw(InstanceOf Str);
1;
[download]

...leads to:

Use of uninitialized value $roles[0] in sort at
C:/Perl/site/lib/Role/Tiny.pm line 199.
Compilation failed in require at C:\path\run.pl line 6.

But this one...

package MyParseExcel;
# use Spreadsheet::ParseExcel;
use Moo::Role;
use MooX::Types::MooseLike::Base qw(InstanceOf Str);
1;
[download]

...works. In Role::Tiny i see...

sub _composite_info_for {
 my ($me, @roles) = @_;
 $COMPOSITE_INFO{join('|', sort @roles)} ||= do { #  <-- 199
   _load_module($_) for @roles;
   my %methods;
   foreach my $role (@roles) {
     my $this_methods = $me->_concrete_methods_of($role);
     $methods{$_}{$this_methods->{$_}} = $role for keys %$this_methods
+;
   }
   delete $methods{$_} for grep keys(%{$methods{$_}}) == 1, keys %meth
+ods;
   +{ conflicts => \%methods }
 };
}

Perhaps i found another module that can't with Moo? This was my doubt using Moo: Long time used modules don't work as expected. Hope i don't miss something.

Thank you for your patience and help.
