Sweet.js prefix a match in a template

Given this macro 

macro type {
  case {_ $attr } => 
  {
   return #{ 
    var a = obj.some$attr
   }
  }
}

type Attr

I'm trying to get this output: 

var a = obj.someAttr;

But what I get is 

var a = obj.some$attr;

Adding any non alphanumeric character between some and $attr correctly outputs the bound value.

Ok just figured out how to do this

enter code here

macro type {
  case { $mName $attr } => 
  {
    var wrapperName = makeIdent('some' + unwrapSyntax(#{$attr}), #{$mName});
    letstx $x = [wrapperName];
    return #{ 
       var a = obj.$x
    }
  }
}
