Is there any real reason to use "const"?

Yeah, really working towards accepting that but I'm getting 
closer and closer each day...

Yeah, that's classic! Tbh, either force your users to use curly 
brackets or find a python like system that will not cause these 
types of errors. In my language this will be:

for i in 0..2:
  // foo()


Ending up having an empty "for" statement and executing "bar()" 
only once.
