problem with #pragma strict and Function type

Question

Is it possible to call a coroutine stored in a variable and use #pragma strict at the same time? And I'm sorry if this has already been answered or the question does not make sense.

 #pragma strict
 
 function Start ()
 {
     StartCoroutine(coroutineFunction(1.0f));
     //works with #pragma strict
 
     var testSimpleFunction : Function = simpleFunction;
     testSimpleFunction(1.0f);
     //works with #pragma strict
 
     var testCoroutineFunction : Function = coroutineFunction;
     StartCoroutine(testCoroutineFunction(1.0f));
     //does not work with #pragma strict
     //BCE0023: No appropriate version of 'UnityEngine.MonoBehaviour.StartCoroutine' for the argument list '(Object)' was found
 }
 
 function coroutineFunction (waitFor:float)
 {
     yield WaitForSeconds (waitFor);
     Debug.Log("coroutineFunction");
 }
 
 function simpleFunction (simpleNumber:float)
 {
     Debug.Log("["+Time.frameCount+"]simpleFunction :"+simpleNumber);
 }

You can let type inference take care of the correct type for you (which works fine with #pragma strict; type inference is not dynamic typing):

 var testCoroutineFunction = coroutineFunction;
 StartCoroutine(testCoroutineFunction(1.0));

If you wrote out the type explicitly, it would be this:

 var testCoroutineFunction : function(float):System.Collections.IEnumerator = coroutineFunction;
 StartCoroutine(testCoroutineFunction(1.0));

I know this thread is pretty old but hoping someone could shed some light.

I've followed Eric5h5's example but just can't seem to get it to work. The following code gives the error "Cannot convert 'function(): System.Collections.IEnumerator' to 'System.Collections.IEnumerator'."

I've tried all different combinations of type for the First() function but no dice:

 var coroutine : System.Collections.IEnumerator;
 
 function Start()
 {
     coroutine = First;
     yield StartCoroutine(coroutine);
     print("Done!");
 }
 
 function First() : IEnumerator
 {
     print ("First!");
     yield WaitForSeconds(2.0);
 }

Sorry, that was a typo in my second example...should have been:

 var testCoroutineFunction : function(float):System.Collections.IEnumerator = coroutineFunction;
