Line 105:
Having done some ALGOL programming in the depths of antiquity on a safer version of ALGOL, there are a few things that you need to understand.
* call by value isn't the default you must ask nicely
* procedure call syntax doesn't require () unless you have arguments, hence you can not tell if x is a variable or a function call from looking
* returned values are just assigned to variables representing the function and are subject to scoping conventions
* running with scissors didn't get you any warnings from your Mom
