Subject: Re: [PHP-DEV] [PATCH] Optional scalar type hinting
From: sam@sambarrow.com (Sam Barrow)

I have thought about this, using obects for all variables, but all of
the extra code amounts to alot in a large application, and when using
hundreds of small strings and integers scattered throughtout your
application, this would cause a serious performance drop.
