Bug description:Global/namespace constants are not hoisted
Description:
------------
"const" Declarations outside a class were introduced in PHP 5.3, and they
only
support static "compile-time" expressions, unlike define().
Function and classes declarations are hoisted to the top of the file, so
you can
call them before the line they are defined in. This doesn't happen
with "const", although it's expected as a matter of consistency. This leads
to
the following odd problem:
<?php
namespace foo;
func(); // Warning, and prints "NOT_HOISTED"
const NOT_HOISTED = 123;
func(); // prints "123"
function func()
{
echo NOT_HOISTED;
}
Please make "const" consistent with the rest of the language, and hoist it
together with function and class declarations.
Expected result:
----------------
To print "123" in both cases, no warning.
Actual result:
--------------
Referring to a const before the line it's declared in results in an error
and
magical string casting (as if it doesn't exist).
