}
)))))))))))))))))))))))))))
What is the expected output?
Silent (successful) compilation.
What do you see instead?

This problem initially revealed itself when the argument types were
more complex -- chan(Int) or [](Int) -- but it's reduceable to just
the (superfluous, at least in this example) bracketing.
Exchanging the two function definition causes the error to additionally
appear inside ok as well as bad.
It /looks/ like the bracketing is being injected into the type at its
first appearance and persists after that.
