Fails to parse classes with typed constants

[davidrans]

It looks like files that have typed constants are not parseable by the latest version (3.1.5).

Input file:

<?php

class Test {
   private const int MY_CONST = 3;
}

Error:

SyntaxError: Parse Error : syntax error, unexpected 'MY_CONST' (T_STRING), expecting '=' on line 4
