Ecstasy's defines [https://github.com/xtclang/xvm/blob/master/lib_ecstasy/src/main/x/ecstasy/Boolean.x an enumeration named Boolean], which contains the values <span style="background-color: #e5e4e2"><tt> False </tt></span> and <span style="background-color: #e5e4e2"><tt> True </tt></span>.

In EGL boolean is a primitive type, however it acts the same as an integer (type int). A boolean and an int accept integer values aswel as true and false keywords (which represent resp. 1 and 0). A boolean is always true except when it has value 0 (or keyword false).
