Return in function parameter initializer

[Jack-Works]

Is this allowed?

function x(y = do { return true }) {}

See the readme:

return is allowed even within function parameter lists, as in function f(x = do { return null; }) {}.

Hmm, can we ban it? It seems like break or continue in the for loop heads. And it's also hard to implement as the method in #63

The problem is that you'd need different rules just for when the do expression is used in default parameter position. Whereas the restrictions to break and continue apply to all do blocks.

Can you give an example? I didn't catch your meaning
