Is it expected a "+" sign in an object's key field to be translated into a function?

[ceremcem]

Is this behavior expected:

a = 
  +: "x"
  -: "y"

a = [
  +(function(){
    _: return "x";
  }()), -(function(){
    _: return "y";
  }())
];

I would definitely expect the following output:

a = {
  "+": "x",
  "-": "y"
};

Isn't LiveScript dead now? It hasn't had a release in over 2.5 years at this point.

Definitely.
For the issue at hand, I don't think you can really expect to be able to use operators as object keys.
What you wrote is basically

a = 
  +(: "x")
  -(: "y")

Thanks. Shouldn't this behavior changed? Why would somebody use an operator as an operator while defining an object?

You're not defining an object, you're defining an array, like this:

a =
  1
  2

The fact that you can treat a label as an expression is definitely a bit weird, but it's not only in this case:

$ lsc -bce '+:1'
+(function(){
  _: return 1;
}());
