Summary: dict('') doesn't raise a value error

Initial Comment:
The dict function will theoretically accept any sequence 
or bounded iterable that yields (key, value) tuples.

A side effect is that dict('') is valid - producing an emtpy 
dictionary.

dict(x) where x is *any* string other than '' fails with a 
ValueError. I suggest that dict('') ought to produce a 
ValueError to as a string is *never* a valid input to the 
dict function.

The current situation allows obscure errors to pass 
unnoticed.
