The following statements represent my understanding of type systems (which suffers from too little hands-on experience outside the Java world); please correct any errors.
This is a pretty accurate reflection of my own understanding of the topic of the static/dynamic, strong/weak typing discussion. In addition, you can consider those other languages:
In languages such as TCL and Bourne Shell, the "main" value type is the string. Numeric operators are available that implicitly coerce input values from string representation and result values to string representation. They can be considered examples of dynamic, weakly typed languages.
Forth may be an example of a static, weakly typed language. The language performs no type checking of its own, and the main stack may interchangeably contain pointers, integers, strings (conventionally represented as two cells, start and length). Inconsistent use of operators can lead to either interesting, or unspecified behavior. Typical Forth implementations provide a separate stack for floating point numbers.
