Oh, HA! Okay, that makes sense. "constant in the JavaScript implementation" -- meaning updating it requires rebuilding Decker from source? Or is it configurable?

Launch Decker, see the default screen with the message to create a new deck, and activity monitor shows Decker at 50% of a CPU. M1 MacBook Air in case it matters.

Interesting -- I'm not terribly familiar with list generation: I've played with Python, so I know it's a thing, but LiveCode has nothing like it built in, and I would never do something like

repeat with i = 1 to 1000000
    put i,"" after aList
end repeat
repeat for each item i in aList
    -- do something
end repeat

I just checked and found that the while loop was even slower :-)

I'm not sure this accomplishes the same task, albeit that the task is synthetic in the first place, but in any case, this is about 20x faster:

on click do
range 10000000
 alert["Done!"]
end

Lil performance question: I have used LiveCode for years, and its built-in language is not fast. So when I try out a new language, the first thing I do after Hello World is a for loop to get a sense of the speed of the language. I tried that with Lil on an M1 MacBook, and found that 

on click do
each x in range 1000000
end
 alert["Done!"]
end

takes about 2 seconds to run. This is about 30x slower than even LiveCode. This is not a criticism, just a question: any thoughts on ways to speed up Lil?
