They were used inconsistently. I originally put them in when the
'external' interface was larger, and I only put them on the external
interface. I've been removing them for internal calls.

These checks are really just a way to get round perl's inability to
check functions calls at 'compile' time. In practice, though, the lack
of type information makes them of limited use. For example, if I changed
the second argument to be a Sys::Virt handle, it wouldn't notice. In
practise, they haven't been catching the errors I've actually been
making. In short, I've gone off these checks.
