the topic says most of it. What do you think about deprecating the global keyword and $GLOBALS with it? Together with this making $_REQUEST, $_GET and $_POST read-only as they should be used only to read-only anyway.

-1 here. No question that if you were developing a new language with similar design goals to PHP (but learning from the missteps), you'd probably make the superglobal analogues read only and skip the idea of $GLOBALS altogether, but there's just too much code out there that relies on these "features" working.

There were many apps which relied on register_globals but register_globals was introduced. There were many apps which relied on references in PHP4, but the object model changed in 5, references too. There are apps which rely on magic_quotes, but magic quotes are deprecated. When some feature is changed or deprecated there will always be applications that need to change.
