Literals

Literal values represent specific instances of a type embedded directly into an expression like the integer 1, the record {x:1.5,y:-4.0}, or the mixed-type array [1,"foo"].

Any valid SUP serialized text is a valid literal in SuperSQL. In particular, complex-type expressions composed recursively of other literal values can be used to construct any complex literal value, e.g.,

• record expressions,
• array expressions,
• set expressions,
• map expressions, and
• error expressions.

Literal values of types enum, union, and named may be created with a cast.
