I’m posting this first in the forum to see response before posting as a formal issue. Proposal This is a proposal to introduce a new keyword ends (or endall) as a terminal point to resolve the end of nested loops|conditionals. Why It’s a common code occurrence to have multiple levels of loops an…

People make mistakes now Very true. I’m definitely one of those :joy: but just might not be what you intended That’s exactly my fear. It would compile with the wrong logic, and that might be a lot more difficult to track down. As opposed to just not compiling with the “missing end” keyword. I…

[image] jzakiya: All 3 examples are syntactically equivalent, whose standard format would be: Why? Care to explain the algorithm?

Oh, there’s a third way to interpret it: class Foo def bar while true ends if foo while true ends

Depends on how you set your parsing rules. But again, you can already write syntactically ambiguous code. But also of course, being the smart (non-masochistic) programmer, you’d never intentionally write ambiguous code you intended to use. But maybe if you’re a malicious hacker… But you can alread…

[image] jzakiya: But again, you can already write syntactically ambiguous code. Can you share an example of that?

From your example, there’s no context to evaluate if the if...end statement would be a dangling illegal snippet in that form, so depending on context, the compiler would flag it, or you would (of course) test your code to confirm it was working correctly. I have to go out and live life now. I’ll …

[image] vlazar: In fact now when my eyesight is not so good anymore having end instead of } is helpful for me in terms of being easy to spot the code structure. Haha, yeah, my poor eyesight is the reason I prefer “end” over “}”. it’s just easier to identify than a single character.

Visually it is a good syntactic sugar and I think there is a way to call a strict rule of use (example: last open => first closed). It’s simple to understand. But on the other hand it’s a big source of mistakes. def render(truthy : Bool, show_msg : Bool = false) return "ok" if truthy thing do …

I think someone previously proposed introducing endd (two ends), enddd (three ends), etc :-)

Can you share an example of that?
