Hi,

just trying to canvass support for the ability to enforce declaration of variables as with perl's use strict:

If you want to emulate perl's "strict" mode just add an error_handler 
() that will catch `E_NOTICE` relating to undefined variable, constant,  
array key usage and convert them to fatal errors.

No, it doesn't do the same thing, it won't pick up the following:

	$fo0 = 'bill';
	...
	$foo = 'ben';

One is a typeo.

Both of these represent valid syntax as far as I am concerned and  
should not generate errors.
