strong typing
<programming> Strict enforcement of type rules with no exceptions.
Incorrect type usage can be detected either at run time or at compile time.
Strong typing catches more type errors than weak typing, resulting in fewer hard
errors. In a strongly typed language, conversion between types requires the use
of explicit conversion functions as opposed to implicit type coercion.
Typing strength is a continuum; ML is more strongly typed than Java, which is
more strongly typed than C.
Strong or weak typing is independent of the choice between static typing and
dynamic typing. Among strongly typed languages, Ada, Java, Haskell and ML are
statically typed, whereas Python and Ruby are dynamically typed.
