It's not directly possible the way you write it, but you can do something similar using Function.apply.

You have to either pass the arguments as positional, and then you need to know the order:

I am not sure if I can even return the result from this closure as it is argument to winit's function.

No you can't, the type of the event loop handler is:

The slist.enumerate() create a new instance of EnumeratedSequence<[String]>

To create an instance of EnumeratedSequence, call enumerated() on a sequence or collection. The following example enumerates the elements of an array. reference

If you remove the .enumerate() produce the same result, any st has the old value. This occurs because the for-in loop generates a new instance of IndexingIterator<[String]>.

Whenever you use a for-in loop with an array, set, or any other collection or sequence, you’re using that type’s iterator. Swift uses a sequence’s or collection’s iterator internally to enable the for-in loop language construct. reference

About the questions:

• You would be able to remove all the elements and still perform the loop safe because a new instance is generated to perform the interactions.
• Swift uses the iterator internally to enable for-in then there's no overhead to compare. Logically that the larger the array the performance will be affected.

I solved this particular issue by making event_loop of type Option<()>> and the run method invoking self.event_loop.take().unwrap().run(...). Unfortunately I really dislike the semantics of this solution since in theory the event loop exists during the entire lifespan of the window and my solution leaving a None in its place doesn't feel right at all.

You need to know the difference between ** on dictionary and ** in function definition.

• ** on dictionary, like func(**d) means "pass the key-value pairs in the dictionary as additional named arguments to function func."

Print statement in the line 6 has nothing to do with functionality of the code to print the Fibonacci series but it just changes the position of the cursor to the next line, so that next print statement in the same script would be executed in next line. Requirement for this arises because in the print statement of line 4 we have changed the default value of optional argument of print statement from end='\n' to end=' '. '\n', is the newline character which represents the cursor has been moved to new line.

This answer is based on my comments provided on the GitHub issue which is a repeat of the OP's question. I'm providing the below for completeness' sake.

Try using the input function for the ForEach activity (make sure that the selected syntax is JavaScript):

input('PayLoad').ApproverList

This will get the input named "PayLoad".

I don't know if Liquid is supposed to work. From a UX point of view, we should either make sure it does, or not even allow that option if it doesn't.

In this code, the lambda function "sees" the argument x and the variable n, which is in the lambda's closure:

You're getting a different value because of L=[] default value and it is mutable. The tutorial link you provided there clearly stated that

• Default value is evaluated only once
• the default is a mutable object such as a list, dictionary, or instances of most classes

So, When you pass another L=[] in your f() function then L=[] is initiating for a new one and return a single result. But after calling f(4) it's getting to default function and return update result
