AstView variable and function hierarchy display appears incorrect

[GoogleCodeExporter]

What steps will reproduce the problem?
1. See screenshot for sample program - specifically create a variable of a 
predefined function type, or a function that uses only one predefined variable 
type as parameters

eg example program

package main

type (
    FT      int32
    USEFUNC func(FT, FT) FT
)

var (
    f    USEFUNC
    a, b FT = 1, 2
)

func main() {
    f = f21
    println(f(a, b))
}

func f21(a, b FT) FT { return a + b }

func f11(a int) int { return a * a }

2. Compile and observe the "Golang Ast View" display
3.

a. Function "f21" appears as a sub-element of type FT - I would have expected 
it to appear under functions.

b. variable "f" is defined as type "USEFUNC", it appears as a normal variable, 
not under the "USEFUNC" display

What is the expected output? What do you see instead?
...It's not clear exactly what rules are being used to generate the abstract 
syntax tree - appears to be based on return type for functions. But in the 
given example f is a function of type USEFUNC with return type FT but appears 
under neither.

Using version X10 (1.5625) on Windows XP SP3 , x86

Please provide any additional information below.
