Have you tried something like this:

你尝试过这样的事情：

@mixin createNumbered($num, $className){
    @for $i from 1 through $num {
        .#{$className}-#{$i} {
            @content;
        }
    }
}

@include createNumbered(10, 'foo-bar'){
    color: white;
}

更新：

@mixin createNumbered($num, $className){
    $foo : '';
    @for $i from 1 through $num {
        $foo : $foo + '.' + $className + '-' + $i + ', ';
    }
    #{$foo} {
        @content;
    }
}

@include createNumbered(10, 'foo-bar'){

Keep it simple, soldier!

保持简单，士兵！

%foo {
  foo: bar; }

@for $i from 1 through 10 {
  .offset-by-#{$i} {
    @extend %foo; }}

UPD You can also have individual styles with this approach:

UPD你也可以用这种方法获得个人风格：

%foo {
  foo: bar; }

@for $i from 1 through 10 {
  .offset-by-#{$i} {
    @extend %foo;
    margin-left: 50px * $i; }}

Which results in the following CSS:

这导致以下CSS：

.offset-by-1, .offset-by-2, .offset-by-3, .offset-by-4, .offset-by-5, .offset-by-6, .offset-by-7, .offset-by-8, .offset-by-9, .offset-by-10 {
  foo: bar; }

.offset-by-1 {
  margin-left: 50px; }

.offset-by-2 {
  margin-left: 100px; }

.offset-by-3 {
  margin-left: 150px; }

.offset-by-4 {
  margin-left: 200px; }

.offset-by-5 {
  margin-left: 250px; }

.offset-by-6 {
  margin-left: 300px; }

.offset-by-7 {
  margin-left: 350px; }

.offset-by-8 {
  margin-left: 400px; }

.offset-by-9 {
  margin-left: 450px; }

.offset-by-10 {
  margin-left: 500px; }
