Styling of parens

[benkb]

hi,
Going through the code of raven.sc I've noticed that two different are used when closing s-expressions

 (if bla
   (do this)
   (do that))

vs.

(if bla
  (do this)
  (do that)
)

when it comes to let expressions, there is

(let ((x a)))

vs.

(let ([x a]))

Are there any particular reasons which led to these different styles?

I think it's no reason but two particular code style of contributors.

for me, it's the first one.
