Subject: Re: [PHP-DEV] Re: Question about superglobals
From: sam@sambarrow.com (Sam Barrow)

I don't understand, people keep telling me this can cause problems so
it's trash. Really? Functions and variables can cause problems too. Not
to mention user input. Programming is not easy, but the more flexible it
is the better. I think it's up to the programmer to keep track of his
variables, rather than us limiting his functionality, just incase he
makes a mistake.

Any programmer can write bad code and it won't work. If he uses
superglobals he should understand that he needs to document them, it's
that simple. If that's too difficult, don't create a superglobal then,
great.

And if this isn't good enough, fine. Require an underscore for
superglobals to differentiate them even more. I'll write the code
myself, no problem.
