unless String is a class you defined that won't work at all. basic data types
cannot be hinted (e.g. bool, int, string, float)

for a split second I was about to say a word start with 'bull', but Marcus
is more or less correct - typehints for classes has existed since the beginning
of php5, the ability to typehint arrays is aparently being included in php5.1
(still in beta).

thanks Marcus for the heads up. :-)

=================

now don't get me started on the fact that 'they' pulled the plug on being able
to do they following - I feel the breath of some purist overlord breathing down
my neck:

class Test { /* ... */ }
function foo(Test $t = null) { /* ... */ }

(the above worked in the first few betas of php5.0)


if a php 'God' reads this (and at least one of you is kind enough to grace us with
his presence on this list) - please reconsider allowing typehints with defaults of
NULL (only NULL and nothing else is more than enough for me!).
