Q:

More precedence/specificity to CSS class in LESS

I've a LESS code like: 
.block__element {
  background: red;
  &--modifier {
    background: yellow;
  }
}

I want more specificity to .block__element--modifier such as:
.block__element.block__element--modifier {
  background: yellow:
}

So that it can overrides some other styles.
I can achieve it by:
.block__element {
  background: red;
  &--modifier.block__element {
    background: yellow;
  }
}

I want to know is there any easy way?

A:

.block__element {
    background: red;
    &&--modifier {
        background: yellow;
    }
}
