My apologies, I haven't used Coro myself but from the documentation if you are right then it is all very misleading as it does appear to provide multithreading and is a replacement for threads and threads::shared. If you read Audrey Tang's review of Coro:

Wow, I can't believe no-one had reviewed this module. In short, this is what Perl Threads should work like. After the fragile-but-fast Perl 5.5 threading thesis, and the slow-but-reliable Perl 5.6 ithreading antithesis, this is the perfect synthesis that gives you a fast and reliable threading model. Highly recommended.

One would think so no? Sorry for my ignorance.
