Removing redundant braces.

[gilch]

In #844 @paultag mentioned fixing double square brackets throughout the language. Besides, let #713 (which may be removed altogether #844) I am also aware of double brackets in defclass #850, import #851, with #852 , and cond #830. Are there more I am not aware of?

I added new issues for those that didn't have them, rather than adding them all here.

Would be really cool to have a tool/script that traverses through a directory tree and makes these changes to hy-code. Probably wouldn't be too difficult to write?

👍 for cleaning up the language a bit, even when it breaks existing code.

I can teach hydiomatic to add these kinds of suggestions. It can't automatically rewrite the code for you, though. That'd be a different (and useful) tool.

For the record, only #830 is left now. I'm closing this, so we have only one issue to track further. Added that to the milestone.
