I don't know why we can do this instead:
if(foo in ["alpha", "beta", "delta"] ) {
}
basically have an opIn operator x in y -> y.opIn(x)
U* opIn(T, U)(T key)
can define in runtime for arrays, and allow custom ones to be
defines
and
if(1 < x <= 10) {
}
I remember this being shot down before...
Both of these are easier to read, and are more natural. They
also cover more cases.
