Example of error:

auto partial_application () {
    // definition of a basic function on 3 parameters using lambda syntax
    auto basic = (float a, float b, float c) => a + b / c;

    // partially apply value to basic
    import std.functional : partial;
    alias partial!(basic, 1) apply1;

    return &apply1;
    // Error: partial(Ts...)(Ts args2) is not an lvalue
}

void main(string[] args) {

    auto test = partial_application();

    import std.stdio : writeln;
    writeln("result: ", test(1, 2, 3));
}

--- Comment #3 from ZombineDev <petar.p.kirov@gmail.com> ---
Since the https://github.com/dlang/phobos/pull/6497 was merged, a fixed version of the example above compiles:

auto partial_application () {
    // definition of a basic function on 3 parameters using lambda syntax
    auto basic = (float a, float b, float c) => a + b / c;

    // partially apply value to basic
    import std.functional : partial;
    alias partial!(basic, 1) apply1;

    return &apply1; // now OK, didn't compile before
}

void main(string[] args) {

    auto test = partial_application();

    import std.stdio : writeln;
    writeln("result: ", test(2, 3)); // 1 + (2/3) = 1.66667
}

I see no reason why the GitHub -> Bugzilla integration didn't close the issue automatically, so I'm closing it manually.

It seems, this was not actually closed. Closing it now.
