> It is maybe not very intuitive that Expression::Bind would require an
> ExecContext and so we never provided one. However, when binding expressions
> we need to lookup kernels, and that requires a function registry. Defaulting
> to default_exec_context is something that should be done at a higher level
> and so we should not allow ExecContext to be omitted when calling Bind.
> Furthermore, [~rtpsw] has suggested that we might want to split
> Expression::Bind into two variants. One which requires an ExecContext and
> one which does not (but fails if it encounters a "call").
