Strange @__class calling behaviour

[fillest]

class Test
  new: (param) =>
    print param

  clone: =>
    assert @__class == Test
    @__class 'test2'
    Test 'test3'
    c = @__class
    c 'test4'

t = Test 'test1'
t\clone!

prints:

test1
table: 0x12e8c40
test3
test4

Is it a bug? I think calling @__class should work same as assigning @__class to a variable and then calling it.
Btw it translates to

      assert(self.__class == Test)
      self:__class('test2')
      Test('test3')
      local c = self.__class
      return c('test4')

It's not a bug, whenever you call a name preceded by @, then the value of @ is passed in as the first argument.

@hello "world"

is the same as

self.hello self, "world"

So the same rules apply to @__class.

The special form @@ is a shortcut to @_class like @ is a shortcut for self, but when you call @@ nothing is passed in as the first argument. So you can do:

@@ "test2"

To make a new instance of the current class. http://moonscript.org/reference/#_and__values

Aah ok thx.
Btw seems http://moonscript.org/reference/ is being too agressively cached. I opened the link, and there was no "@@" and it appeared after ctrl+f5. Firefox, linux.
