混入也可以是值！你不能直接将混入写作值，但可以将混入的名称传递给 meta.get-mixin() 函数以获取它作为值。一旦你有了混入值，就可以将它传递给 meta.apply() 混入来调用它。这使得库可以以复杂而强大的方式进行扩展。

SCSS Syntax

@use "sass:meta";
@use "sass:string";

/// Passes each element of $list to a separate invocation of $mixin.
@mixin apply-to-all($mixin, $list) {
  @each $element in $list {
    @include meta.apply($mixin, $element);
  }
}

@mixin font-class($size) {
  .font-#{$size} {
    font-size: $size;
  }
}

$sizes: [8px, 12px, 2rem];

@include apply-to-all(meta.get-mixin("font-class"), $sizes);
