1.2 Primitives
Arguments to a fact subject or predicate may have one of three primitive types:
integer, string, or sequence.
Integers
Integers may be declared in decimal, hexadecimal, or binary by using the
number system appropriate prefix (0x for hexadecimal, 0b for binary).
Strings
Strings may be quoted or unquoted, although unquoted strings may not include
the characters right parenthesis, right square bracket, or comma. Argument
strings support escape sequences using the backslash character.
Sequences
Sequences are lists of primitive types, enclosed in square brackets and delimited
by commas.
