You can't. The object doesn't not provide a means of accessing the value you pass to init. But if it provided an accessor, I'm with Anonymous Monk: use arrows.

Say the accessor is named "init", 

$pool->init   # Returns the array ref passed to the constructor.
  ->[0]       # Access to the first element of the referenced array.
  ->();       # Call the referenced sub.
