Hi,

With namespaces and "use" we'll be introducing a new kind of discrepancy =
between a string reference to a function, and the short "use"-enhanced =
name for the same function. This becomes very painful, when I want to =
load a function before I run it.

Today I would do (due to lack of function autoload.. hopefully one =
day..):  =20

F::loadFunc('Foo_Bar_Baz'); =20
echo Foo_Bar_Baz();

Tommorow I could attempt to do:

use Foo\Bar as B;
F::loadFunc('B\Baz'); <-- failure, strings are not resolved agains the =
use statements
echo B\Baz();=20

so it becomes:

use Foo\Bar as B;
F::loadFunc('Foo\Bar\Baz'); <-- works, but negates some of the use for =
"use"...
echo B\Baz();=20

I suggest we introduce a new construct which will return a string when =
passed any identifier to resolve against the current file's use clauses:

nameof Symbol\Name;

With this identifier, the above example can be "normalized" to the =
following code:

use Foo\Bar as B;
F::loadFunc(nameof B\Baz); <-- will send 'Foo\Bar\Baz' as the argument
echo B\Baz();=20

NOTE: As a side effect this means less direct writing of string =
function/class names, and less complaints about \ being the escape =
characters.

Regards,=20
