+Style #2
+==============================
+
+Constraints:
+
+- Existence of an all-important data stack. All operations
+  (conditionals, arithmetic, etc.) are done over data on the stack
+
+- Existence of a heap for storing data that's needed for later
+  operations. The heap data can be associated with names
+  (i.e. variables). As said above, all operations are done over
+  data on the stack, so any heap data that needs to be operated upon
+  needs to be moved first to the stack and eventually back to the heap
+
+- Abstraction in the form of user-defined "procedures" (i.e. names
+  bound to a set of instructions), which may be called something else
+  entirely
+
+Possible names:
+
+- Go-Forth (as in the Forth programming language)
+- Stack machine
