Writing Idiomatic Scala with Infix Modifiers
In Scala, the infix modifier is applied to method and type definitions to signal their intended use in infix position, even if they have alphanumeric names. This ensures that such methods or types can be used naturally in expressions. An infix method must have exactly one parameter in its first parameter list. Infix modifiers can also be applied to types, traits, or classes with exactly two type parameters, allowing them to be used in infix syntax. This feature enhances readability and idiomatic usage in Scala programming, making code more concise and expressive.
This Scala program demonstrates the infix modifier. It includes an infix method multiply defined as an extension on Int, and an infix type Pair. The main function showcases the usage of these infix definitions, illustrating the readability and clarity provided by infix notation in method calls and type usage.
