- bit
- A 'bit' is a boolean value that can hold either 0 or 1. -
- int
- The 'int' type represents a simple 32-bit integer value, such as 5. -
- string
- The 'string' type represents an ordered sequence of characters of arbitrary length. -
- bits<n>
- A 'bits' type is an arbitrary, but fixed, size integer that is broken up into individual bits. This type is useful because it can handle some bits being defined while others are undefined. -
- list<ty>
- This type represents a list whose elements are some other type. The contained type is arbitrary: it can even be another list type. -
- Class type
- Specifying a class name in a type context means that the defined value must be a subclass of the specified class. This is useful in conjunction with the list type, for example, to constrain the elements of the list to a common base class (e.g., a list<Register> can only contain definitions derived from the "Register" class). -
- dag
- This type represents a nestable directed graph of elements. -
- code
- This represents a big hunk of text. NOTE: I don't remember why this is distinct from string!

- DEF
- reference to a record definition -
- CLASS<val list>
- reference to a new anonymous definition of CLASS with the specified template arguments. -
- X.Y
- reference to the subfield of a value -
- list[4-7,17,2-3]
- A slice of the 'list' list, including elements 4,5,6,7,17,2, and 3 from it. Elements may be included multiple times. -
- (DEF a, b)
- a dag value. The first element is required to be a record definition, the remaining elements in the list may be arbitrary other values, including nested `dag' values. -
- !strconcat(a, b)
- A string value that is the result of concatenating the 'a' and 'b' strings.
