no, you have to cast your mind back to BASIC to find a language designed
to be 'easy to use' that completely masks any possible knowledge of what
exact type of variable is in play at any given point.

And whose specification is not unambiguous on that point. Or was that
JavaShite (TM).

it's less untyped, than randomly casting types about like pearls before
swine.

whether '3' is in integer, a character, a string or a floating point
number, is entirely down to context. And will change with it, too.

Its known as programming for dummies, and its very fashionable.
