Are the languages with a sound type system a sub set of strongly typed languages?
回答1:
What is a sound type system? Do you consider static typing more "sound" than dynamic typing? Does weak typing imply the type system being "unsound"? Do you consider C or C++ to be weakly typed because they allow for a number of ad hoc type conversions?
Lua is weakly typed, but the types provided make for asonishing power. Soundness lies in the eye of the beholder.
