Thank you.

It's basically a multiline function call. Not sure how frequently that 
is used with attr_* in practice, but in our big project at work, just 
one out of 190 attr_* declarations is multiline.

So, it happens, but in the vast majority of cases the arguments stay on 
one line. Some projects (like Rails) choose to make several calls 
instead, as a stylistic choice.

I can't really say yet if the lack of support for multiline calls is a 
significant problem, but it is an omission.

Whether to implement it now, or close this bug and wait until another 
bug report, is up to you.

Thanks! Looks good.
