So if you drop the '$' the way that you call a function referenced in variable
'funref' is not:

	$funref()

but

	funref()

However: the PHP parser will take that to be a call to a function named 'funref'.
So you need to change the syntax to, perhaps, something like C:

	(funref)()

I can't see people understanding that.
Stick with what we have.
