last declaration wins with mixins as function??

[bassjobsen]

I try to understand why last declaration wins is not applied when using mixins as function.

I try to compile the following code:

.useasfunction(@input)
{
   @return: @input;
}

p {
.useasfunction(first);
property1: @return;
property1a: @local;
@local:first;
.useasfunction(last);
property2: @return;
property2a: @local;
@local:last;
}

Which compiles into the following CSS code:

p {
property1: first;
property1a: last;
property2: first;
property2a: last;
}

See #1892.

Closing as "expected behaviour" (and duplicate of #1892).
