Hashes can still be created like this using of: foo = {} of String => Int32 foo["neat"] = 42 And then is still used with case statements when you just have a single line after the when/in. case someVar when 9 then doSomething when 13 then doSomethingElse else puts "Not 9 or 13" end case someEnum…

No they definitely aren’t deprecated. What gave you that idea?

I find it interesting that then is only ever used in case and select statements, it would be nice if we replaced the current ternary operator with if..then..else, and it would make more sense since we can already use if statements as expressions.

if a then b else c would be quite confusing as ternary expression compared to a regular conditional expression if a; b else c end considering the final end keyword. And it’s not even shorter, so really there’s no point in that. Just use the regular if.

I don’t see how it would be confusing, I often have trouble reading code like this: foo = bar? ? baz : qux which would be much more readable as foo = if bar? then baz else qux. Using a regular if statement forces extra whitespace by the formatter even when trying to use the semicolon form: foo = if…

foo = bar? && baz || qux would also do the trick :S EDIT: Kinda meant this as a joke, but if you find this syntax better than bar? ? baz : qux then :+1:.

Sure, then could be allowed as separator between condition and then branch. But if you think about the general case, I think it is often a good solution to split this into multiple lines. In your example you’re using very short identifiers. In most real use cases, they are likely much longer. Mayb…

In the absence of ‘then,’ if statements lack a sense of ceremony, and it is hoped that ‘then’ remains an optional element Ritual is more important than simplicity Why did I choose Ruby over Python? It’s because Python, in its pursuit of simplicity, omitted ‘end,’ and it lost the ceremonial aspect …

[image] gs412: ceremonial aspect of programming OK, haven’t heard that one before. I gather that you don’t use and editor that automatically adds an end when typing do?

@Xen
The sense of ceremony is not only in writing, but also in reading
