Duplicated error type.

[corona10]

Got:

Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 FIXME line of source goes here
TypeError: TypeError: 'all() takes exactly 1 argument (3 given)'

Expected:

Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 FIXME line of source goes here
TypeError: 'all() takes exactly 1 argument (3 given)'

Line 105 in 50cd487

vm.curexc.Type = exception.Type()

gpython/vm/eval.go

Line 104 in 50cd487

vm.curexc.Value = exception

To fix this issue, vm.curexc.Typeshould not be refernced since vm.curexc.Value
already build the exception message.

But I don't know where it works, can you guide it please?
Thanks!

I think you want to change this in py/exception.go

// Dump a traceback for exc to w
func (exc *ExceptionInfo) TracebackDump(w io.Writer){
	if exc == nil{
		fmt.Fprintf(w, "Traceback <nil>\n")
		return
	}
	fmt.Fprintf(w, "Traceback (most recent call last):\n")
	exc.Traceback.TracebackDump(w)
	name := "<nil>"
	if exc.Type != nil{
		name = exc.Type.Name
	}
	fmt.Fprintf(w, "%v: %v\n", name, exc.Value)
}
