- The following built-in s-exp's are supported:
-
- list = (and list*)
- perform an intersection of a number of lists, and return that.
-
- bool = (and bool*)
- perform a boolean AND of boolean values.
-
- list = (or list*)
- perform a union of a number of lists, returning the new list.
-
- bool = (or bool*)
- perform a boolean OR of boolean values.
-
- int = (+ int*)
- Add integers.
-
- string = (+ string*)
- Concat strings.
-
- int = (- int int*)
- Subtract integers from the first.
-
- Comparison operators:
-
- bool = (< int int)
- bool = (> int int)
- bool = (= int int)
-
- bool = (< string string)
- bool = (> string string)
- bool = (= string string)
- Perform a comparision of 2 integers, or 2 string values.
-
- Function flow:
-
- type = (if bool function)
- type = (if bool function function)
- Choose a flow path based on a boolean value
-
- type = (begin func func func)
- Execute a sequence. The last function return is the return type.
