[PHP-DEV] Static method call with single colon results in fatal error, not a parse error?

[Bishop Bettini]

class Foo {
    public static function bar() { echo 'bar'; }
}
Foo:bar();


Note the single colon.  According to 3v4l <http://3v4l.org/Ot3Fk>...

5.2.17 and earlier:
Parse error: syntax error, unexpected ':'

5.3 and later, including 7 and HHVM:
Fatal error: Call to undefined function bar()


Is this really a run-time fatal error?  Unless I missed a memo, surely this
should be a compile time error.
