Shouldn't as in doesn't at the moment.

More philosophically, I was assuming -betterC code can't call non -betterC code
e.g. It uses druntime, although I suppose in the sense that that particular
exception doesn't escape the function I don't know. The spec doesn't say
whether -betterC code can call code using non -betterC features.
