Lispers don't always realize that too many parens/brackets is a code smell in almost any other language. It makes people unnecessarily wary of (stuff (like 'this)).

Its().just().the().same().for().us().lispers().abstractFactoryFactory()

And I wouldn't want to write sql like that ;)

Why not both?

Quasiquote is going into Java 9.

I dunno. If I have a "complex" condition with more than two parts to it, I prefer to be liberal with parenthesis, rather than expect any future maintainer to remember all the operator precedence rules.
