Detached rulesets do not return variables

[SomMeri]

Now I see that detached rulesets do not return variables at all. Following throws compile error:

@detached-ruleset: { 
    @color:blue; //variable NOT returned
};
.caller {
    @detached-ruleset();
    color: @color; 
}

Error:

NameError: variable @color is undefined in C:\data\meri\less4java\commandLineLess\node.js-latest\test.less on line 6, column 12:
5     @detached-ruleset();
6     color: @color;
7 }

Is that how it should be? Mixins are returned as usually. If this is as expected, then the #2064 should be closed too.

Tested on lessc 1.7.3 (Less Compiler) [JavaScript]

Yes, this is what we actually assumed in #2064 (i.e. there it was not some kind of a scope priority issue but just "DR does not expose its variables to outer scope at all"). Hmm, I guess we can close #2064 and keep the discussion here?

I closed the other issue and I am closing this one too. I did not liked the subtle difference in behavior I through I found, but this is not subtle at all. After all, workaround is possible, although somewhat limited:

@detached-ruleset: { 
  .acquire() {
    @color:blue; //variable will be returned
  }
};
.caller {
    @detached-ruleset();
    .acquire();
    color: @color; 
}

Might make sense to re-open if someone has real use case for that.
