Subject: Re: [PHP-DEV] Scalar type hinting
From: dmgx.michael@gmail.com (Michael Morris)

Thank you.

Now I'm going to go work up a detailed RFC for what I posted earlier
with some additional clarification as to when errors should and
shouldn't be thrown.

> OK everyone, it seems that some people have forgotten or missed the origi=
nal agreement that this thread started with. There is a communication disco=
nnect ("strict typing" means horribly different things to different people =
right now). Please read through and understand the following terminology be=
fore continuing to post on this thread. We've agreed to the following terms=
:
>
> - "Strict Typing" means the super strict old C style typing *with no impl=
icit conversions*. (If you really think this is what you want, you are prob=
ably mistaken. Look through prior discussions on this topic. This fails for=
 numerous reasons, including the fact that almost every input to PHP is a s=
tring.)
> - "Weak Typing" means types in the same sense that the PHP documentation =
uses types (for example, the docs indicate substr(string, integer), and sub=
str(12345, "2") =3D=3D "345".) (If you think you want "strict typing", this=
 is probably what you mean.)
> - "No Scalar Typing" should be used to indicate the current system (where=
 there is no provision for hinting at scalar types.)
>
> In addition, if someone potentially new expresses support for "Strict Typ=
ing", please assume that they really mean weak typing unless proven otherwi=
se (this is by far the more likely intent.) Don't get mean, politely clarif=
y terminology so that everyone can be on the same page. If someone still in=
sists that they want "Strict Typing" (as defined above), point them to the =
prior discussions on the topic which explain exactly what the problems with=
 this are.
