Where is the term "strict typing" coming from? I've not seen this used to
describe any type system (doesn't mean it's not been used, but I'd really
like to see the usage so I can understand the label.)

Doesn't weak typing mean that the language implicitly converts types for
use according to a set of rules? The opposite of this being strong typing,
which means the language does not perform implicit conversions.

And, curious about the "No Scalar Typing"?

Sorry for the questions.

Thanks,
