 === Using QueryPerformanceCounter ===
 QueryPerformanceCounter allows even more precision:
-<lang AHK>MsgBox % time("fx")
+<lang AHK>MsgBox, % TimeFunction("fx")
+TimeFunction(Function, Parameters*) {
-time(function, parameter=0){
+	SetBatchLines, -1						; SetBatchLines sets the speed of which every new line of coe is run.
-	SetBatchLines -1
-	DllCall("QueryPerformanceCounter", "Int64*", CounterBefore)
+	DllCall("QueryPerformanceCounter", "Int64*", CounterBefore)	; Start the counter.
-	DllCall("QueryPerformanceFrequency", "Int64*", Freq)
+	DllCall("QueryPerformanceFrequency", "Int64*", Freq)		; Get the frequency of the counter.
+	Function.Call(Parameters*)					; Call the function with it's parameters.
-	%function%(parameter)
-	DllCall("QueryPerformanceCounter", "Int64*", CounterAfter)
+	DllCall("QueryPerformanceCounter", "Int64*", CounterAfter)	; End the counter.
-	return (CounterAfter-CounterBefore)/Freq * 1000 " milliseconds"
+	; Calculate the speed of which it counted.
+	Return, (((CounterAfter - CounterBefore) / Freq) * 1000) . " milliseconds."
