I was able to reproduce this problem, and chatted with Zefram on irc 
about it.  He believes that the problem lies with  To summarize,

"the necessary and sufficient fix is for invoker_ck_entersub to check 
that it's got an entersub op, and skip most of its check-time logic when 
it doesn't"

Also, "invoker ought to behave as a lexically-scoped pragma, rather than 
globally affecting any use of $-"

And, "this is partly down to the means by which invoker hooks the op 
checker, which is via another CPAN module, the combination of the two is 
broken, and will fail when it meets any call checker that rewrites an 
entersub into some other kind of op.  your commit merely introduces 
another such rewriting checker"

I've created
against invoker
