IMHO sigils made sense back when there were a couple of ways to allocate

What really bugs me about `~` is that it conflates the idea of lifetime
and ownership (which is a zero-cost annotation) with allocation (which
is an actual expensive operation to stay away from). This wasn't a
problem with `@`, but it's gone now.
My choice would be to keep `~` in types, but use `new` for allocation:
let foo: ~Foo = new Foo(bar);
