As a non-Ruby programmer, this sounds like it makes it non-obvious whether you're calling a class' method or attribute. Do you end up relying on your editor to help you out ?

“Attributes” in Ruby are just methods that do attribute-like things, so there is no ambiguity: it is always a method.

Every langauge with native support for property setters and getters has the same problem. C# has decent IDE support, in JS we pretend it never happens, Ruby is at least upfront

It's actually nice that it does not matter if it's a function or attribute that your calling in ruby. Check out the Uniform access principle (https://en.wikipedia.org/wiki/Uniform_access_principle).

When used correctly you can write IMHO really clean and concise OOP code where (cascading) changes are easily made.

Where this kills me is ambiguous commas.

    something = [ alpha beta, gamma ]

I have no idea if I just invoked alpha(beta, gamma) and put the result into a single-member array, or if I've got an array with two elements - alpha(beta) and gamma.

Yep you can create ambiguous nasty code like this. It's is clearly not expressing intent, so you would add parentheses.

[dragonwriter]

It's not actually ambiguous; though it is a bit of language-specific syntax to learn.

Agreed. It is the "idiomatic" way of writing code in Ruby. I love Java but writing lambda expressions in Java with deeply nested parenthesis makes the code really ugly and less readable esp with chaining.

As far as I understand, Ruby style is writing the code in the most elegant way to increase readability and (hopefully) reduce chances of bugs.

So what would you expect my example above do, at a glance?

Or is my example something that a good Ruby developer never write at all?

[pavel_lishin]

It's not ambiguous to the computer, but it is ambiguous to a human at a glance.
