Apologies to you Alexey, as the point that you made was very relevant, 
and my reply was a response to a misreading as Felipe as kindly pointed out.

Yes, extending declare would be a more elegant approach, but there is a 
problem with an extended the declare syntax -- statements such as:

    declare( allow_override_builtins = 1);

would generate additional compiler warnings when used on all previous 
versions, and one of my aims was to enable B/C back to PHP 5.3 at least.

Also as declare is a pure compiler construct that only applies to the 
source, there would be no equivalent mechanism for, say, defining a 
namespace-wide set of pragmas without further modifying every source file.
