Yes.

No, it doesn't call any C++ function.

(N.B. I was searching in debug/safe_iterator.h for the 'explicit'
conversion operator you referred to and was confused because I
couldn't find it, which is because the operator for converting to base
is not 'explicit')

I'm not sure why the existing Python code does .cast(itype) when
_M_current is already that type, that seems unnecessary to me, but
I think your fix is correct and OK to commit, thanks.
