When not using namespaces the following code works just fine

Function loadClass ($class) {
    $this->obj = new $class();
}

However, when attempting to implement namespaces:

function loadClass ($class) {
    $this->obj = \classes\$class();
}

Throws an "Parse error: syntax error, unexpected T_VARIABLE, expecting 
T_STRING".  Which is kind of silly, since the corrected function looks like:

function loadClass ($class) {
    $class = '\classes\\'.$class;
    $this->obj = new $class();
}


Upon reading other bugs that query about using dynamic content in namespaces, 
I'm confused as to why the latter example above actually does work if namespaces 
are computed on compile time, when the class isn't known at compile time.

Expected result:
----------------
I kindly request that you be able to use dynamic elements when using namespaces.
