Syntax Error concat a var with modifiers

[enriqueiurleo]

Hi!
I found a syntax error when trying to do something like this:
`<?php

Class Example{
private static $var = 'test' . 'ing';
}
?>`

Doing the same thing outside a class without any modifier works well. But with this example the method p_static_scalar is called in the phpparse.py. After that I couldn't debug very well what is happening but it gaves me a Syntax Error after reads the concat. It does not read the second part ('ing' in this case), at least for what I saw.
