           Summary: Calling a function whose name is obscured by a local
                    variable does not produce an error
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: go
        AssignedTo: ian@airs.com
        ReportedBy: rluble@gmail.com

Small program exhibiting the mentioned error

When calling a function whose name is obscured by a local variable on a *tuple
assignment* statement (as in the example below) no error is produced and the
generated code does not have the function call. 


func test(a int) (int, int) {
  b:=a+1
  return b,a
}

func main() {
    test, a := 1, 1
    c,d := 1,1

    c,d = test(a)
}


The expected behaviour is to produce an error.

gccgo : Fixed bug 49889.
        Now the compiler emits a proper error when a function
        called in a tuple assignment statement can not be
        typed as a function.
