Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Nil(ExprNil)

Numeric(ExprNumeric)

lua numeric literal value

String(ExprString)

lua string literal value

Bool(ExprBool)

lua boolean literal value

Variadic(ExprVariadic)

...

Ident(ExprIdent)

just identifier

Table(ExprTable)

table constructor

Function(ExprFunction)

unnamed function object

FunctionCall(ExprFunctionCall)

function call. prefix(args) or prefix:method(args)

TableIndex(ExprTableIndex)

table[index]. table.index also matches here.

Binary(ExprBinary)

binary operation. lhs OP rhs

Unary(ExprUnary)

unary operation. OP x
