Does codi support coding inside a function

[superhans]

I have similar issues on Vim 8.1 (tested on MacOS Mojave and Ubuntu 16.04) as #31
Essentially, If I type
x=3
I get nothing on the codi pane.
But if I type just :
x on the next line, I get the output (I actually don't mind this behavior). This way, it only prints when I want it to.

But unfortunately, this behavior does not persist when I wrap the above code in a function. Say, I do

def main():
    x = 3
    x
main()

I don't get any output unless I do print(x) instead of just x (which is a pain to type and delete, as shown in figure below). Is there any way I can get the default behavior inside a function? Then I can use codi as part of my main workflow.

vimrc is

The value does not show because your main() does not return any value, so the line in which it is called does not actually evaluate to a displayable expression. You can get the desired behavior by returning the value you want to display. Otherwise, such behavior will only work if the language supports implicit returns, like Ruby or CoffeeScript.
