I think the best solution here is actually to deviate from the expression style
syntax and have an explicit "return" keyword. Then it would be perfectly safe
to have the default guard be ":any". I am not sure, but I think following this
path would also make it possible to have E loops terminate with a return rather
than throwing an exception.
