Creates an IntRange from start to endInclusive if endInclusive >= start, otherwise it creates a downwards IntProgression (with step -1). Note, there is no similar method which uses an exclusive end.

Creates a CharRange from start to endInclusive if endInclusive >= start, otherwise it creates a downwards CharProgression (with step -1). Note, there is no similar method which uses an exclusive end.

Creates a LongRange from start to endInclusive if endInclusive >= start, otherwise it creates a downwards LongProgression (with step -1). Note, there is no similar method which uses an exclusive end.

Use as an infix function within a call to mapOf. Alas, at the time of writing this, Feather cannot guess the type parameters, so you cannot do : mapOf( "Hello" to "world", "Hi", "all" ) But that is the plan! NOTE. Feather currently has an infix operator => which performs the role.
