Following on from the request in https://community.devsense.com/d/2295-to-go-definition-on-callable-params-in-function-call/2, it would be great if this would work:
<?php
namespace A;
function foo() {}
function function call_me( callable $function ) {}
call_me( __NAMESPACE__ . '\\foo' );
__NAMESPACE__ . '\\foo' isn't linked to the function definition, where a non-contatinated string would be (e.g. A\\foo.
I'm not sure if you have the ability to resolve concatenated constants into string literals in this way, but doing so would be a great help!
