Interpolation in Less. How to implement extend through a variable?

Question

Less

The essence of the question is this: a variable of the string type comes into the mixin. You need to call extend with the name of this variable. Example:

.mixin("extend");

.mixin(@variable){
   [email protected](); - вот здесь всё ломается :-(
}

Answer 1

pass detached ruleset there with a direct call to the mixin.

.extend() {
  x:1;
}

.mixin(@variable){
  @variable();
}

x {
  .mixin({.extend()});
}
