--- Comment #1 from Jack Stouffer <j...@jackstouffer.com> ---
This enhancement request makes no sense, as the "in" operator in Python and D
do two completely different things.

To replicate the Python behavior, you can do the following:

import std.stdio, std.range, std.algorithm.searching;

void main() {
    if (iota(1, 10).countUntil(foo(2)) > -1) {
        "yes".writeln;
    }
}

But I don't see why you would want to, as this is much faster:

void main() {
    immutable int temp = foo(2);
    if (temp >= 1 && temp <= 10) {
        "yes".writeln;
    }
}
