in thread variables names used to define variables

There are no references to subs involved in finding methods when it comes to class or object method calling.

Yes there is. Otherwise, this code wouldn't work:

$ perl -Mstrict -e '
package My::Foo;
sub bar { my $class = shift; print "Calling $class->bar\n"; }
package main;
my $class = "My::Foo";
my $method = "bar";
$class->$method();
'
Calling My::Foo->bar

    That's no more a reference than 
        my %hash;
    my $key = "foo";
    $hash {$key} = 1;

    is.

      Although this might be splitting hairs, the Blue Camel disagrees (p. 313):

      Although you're using the name of the method to invoke it indirectly, this usage is not forbidden by use strict 'refs', since all method calls are in fact looked up symbolically at the time they're resolved.

      Unless the author of that passage (Tom Christiansen, I think) also considers hash lookups to be symbolic.
