Product Version = NetBeans IDE 8.2 (Build 201705191307)
Operating System = Windows 10 version 10.0 running on x86
Java; VM; Vendor = 1.8.0_101
Runtime = Java HotSpot(TM) Client VM 25.101-b13

Reproducibility: null

STEPS:
  * In php, start a namespace
  * inside the namespace, create a function with a parameter.
  * Use PHPDoc to describe the function and its parameter, set the parameter's type to callable (@param callable $myCallable)
  * Inside the function, type the $ and the first char of the parameter name.
  * Hit Ctrl+Space and look at the pop-up that suggests the parameter, and then look at the presented type.
  * It shows the function's namespace and the word callable, as if callable would be a class within the namespace.

ACTUAL:
  nothing happens

EXPECTED:
  It shows the type callable, as it would show the type string or int, etc...
