Calculating with Funtions with parenthesis
... but those are commas instead

https://www.codewars.com/kata/525f3eda17c7cd9f9e000b39

similar to the link but with using a comma as a parenthesis...
let me explain:

five(times(one()),plus(one())) == 6 // (5 * 1) + 1
five(times(one(plus(one())))) == 10 // 5 * (1 + 1)

five(times(one(plus(one(times(two())))))) == 15 // 5 * (1 + (1 * 2))
five(times(one(),(plus(one(times(two())))))) == 7 // (5 * 1) + (1 * 2)
five(times(one(),(plus(one(),(times(two())))))) == 12 // ((5 * 1) + 1) * 2

What if we have operation precedence with comma?

I tried to figure how this could works:
Test.assert_equals(five(times(one(plus(one())))), 10)
Test.assert_equals(five(lambda x: x * 1, lambda x: x + 1), 6)
Test.assert_equals(five(times(one(), plus(one()))), 6)

Do you have an idea?

Why this works D: ?
