@media print triggers extend missing?

I found:

@media print {}
.test {
color: red;
}
p {
&:extend(.test);
}

generates:

extend ' .test' has no matches

I had this mistake “extend ’ .clearfix’ has no matches”

less v 2.5.0 on windows/mac

.clearfix() {
  &:before,
  &:after {
    content: " "; // 1
    display: table; // 2
  }
  &:after {
    clear: both;
  }
}

.holder {
  width: 32px;
  &:extend(.clearfix);
}

But after some time in bootstrap less (file utilities.less) I found this

.clearfix { .clearfix(); }

Now it works

@romaroid yes extend doesn’t match mixins yet, so it was a valid warning until you added the extra code.
