    user-defined types that support $(D ++), the range is an input
    range.
 
+   An integral iota also supports $(D in) operator from the right. It takes
+   the stepping into account, the integral won't be considered
+   contained if it falls between two consecutive values of the range.
+   $(D contains) does the same as in, but from lefthand side.
