<blockquote type="cite"><div class="plaintext" style="white-space: pre-wrap;">One thing that I miss sometimes when doing meta programming is being able to hide that a function should be called with mixin.

For example (pardon my lack of creativity):

    // Instead of
    string declare_a() {
        return "int a;"
    }

    int func() {
        mixin(declare_a);
        return a;
    }

    // Could we have?
    mixin declare_a() {
        return "int a;";
    }

    int func() {
        declare_a;
        return a;
    }

I think this could be useful when one is creating Idiom and Patterns, you could hide implementations details.</div></blockquote><br><div>You can do this:</div><div><br></div><div><div>mixin template declare_a()</div><div>{</div><div>&nbsp; &nbsp; int a;</div><div>}</div><div><br></div><div>int func()</div><div>{</div><div>&nbsp; &nbsp; mixin declare_a;</div><div>&nbsp; &nbsp; return a;</div><div>}</div></div><div><br></div><div>but there is no way to exclude mixin before calling declare_a, there is a good reason for that (it is really important to be able to tell when you use mixin and when not)</div>
