Method isTupleVariant

pkg/codegen/match.go:760–770

isTupleVariant determines if a type name represents a tuple variant. Tuple variants use positional fields (Value, Value0, Value1, ...). Struct variants use named fields matching the struct definition. Currently handles: - Result variants: ResultOk, ResultErr (tuple) - Option variants: OptionSome, O

(typeName string)

// TODO: This should lookup variant metadata from a type registry
// instead of hard-coding known types.
func (g *MatchCodeGen) isTupleVariant(typeName string) bool {
	// Result and Option built-in types use tuple variants
	switch typeName {
	case "ResultOk", "ResultErr", "OptionSome", "OptionNone":
		return true
	}

	// Custom enums currently assumed to be struct variants
	// This will be fixed when we have a proper type registry (see action items #5)
	return false
}

// generateHumanLikeAssignment generates code for assignment context (x := match ...).
// Produces: var x TYPE; switch { case ...: x = value }
