           Summary: in array / slice / range / enum / ...

           Version: unspecified
          Platform: All
        OS/Version: All

The in expression can be extended to support things like:

int i;
...

if(i in [1, 2, 3])

or

if(i in [1..5])

or even

enum Color { red, blue, green };
if(i in Color)

It will test for the existence of the element in the container, returning true
if the element is found. If the container is a set of integers, the element
must be an integer. If the set is a string, the element must be a char..
An !in expression also is welcome.

Obs.: also keep the current in expression for associative arrays, returning a
pointer to the element and the opIn and opIn_r.
