Hi, when infix functions are useful ?

[hho]

For creating DSLs or when you want something like an operator function, but with a new name

For example until is an infix function in the standard library to create a `Range`: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.ranges/until.html

[ephemient]

kotlin-stdlib has lots of infix functions: for pair (to), range (until, downTo, step), collection/array (zip, union, subtract, intersect, contentEquals, contentDeepEquals), comparator (then), bitwise (and, or, xor, shl, shr, ushr)

and lots of other libraries have infix functions (e.g. a good chunk of the MockK and Kluent DSLs)

@ephemient Yeah I know but in which cases should I set methods as infix ?
