Re^5: Net::Twitter - fatal , but no error?

[tobyink]

It's claiming that roles don't support array references for around method modifiers... i.e. Moose stuff. It's saying that this doesn't work...

use v5.14;

package Local::Role {
    use Moose::Role;
    around [qw/ a b /] => sub { say "constant access" };
}

package Local::Class {
    use Moose; with 'Local::Role';
    use constant { a => 1, b => 2 };
}

# Should print "constant access" twice
Local::Class->a;
Local::Class->b;

On my machine, the above does work though, so it's likely that you're running a very old Moose/Class::MOP. Judging from Moose::Manual::Delta this may have been introduced in Moose 0.95; current version is 2.0604.

Ah - maybe its an old version of Moose then. I've emailed my host to check up.

Mmm, well they upgraded it, but now I get:

:| Are there any other decent Twitter methods out there? (I prefer OO, as when/if twitter change their method - its a simple case of just updating it).

The key error message is: Attribute (aliases) does not pass the type constraint because: Validation failed for 'ArrayRef[Str]' with value ARRAY(0x21b92a8). Which suggests that some code somewhere is trying to set "aliases" to an arrayref, but not an arrayref of strings. The aliases stuff appears to be part of the internal sugar defined in Net::Twitter::API, so the bug is probably somewhere in Net::Twitter itself - do you have any more of the stack trace from the error message?

Net::Twitter is actually rather good in my experience, so I'd probably recommend persisting with it.
