This looks much better to me. If I understand it right:
- 'untyped' is the equivalent of the debugger's 'untyped variable' 
(never used, can either turn into scalar or into array)

- 'scalar_u' is what the debugger calls 'uninitialized scalar' (scalar 
but no value, can turn into scalar_s or scalar_n, but never into an array).

Thanks. The fixes work fine.
