Do you like the Clojure syntax?

Hi, I'm curious about the general opinion on the Clojure syntax, whether people actually like it or just use it because it provides macros. So I would like to ask you to participate in a poll. Thank You. Here's the link: https://docs.google.com/forms/d/1GSgfkeThpUYlgFVzhhNIgA1JbTilu6S9eudq_Sbxl

Re: Do you like the Clojure syntax?

isolating the syntax from the other features of the language is a like removing a part from a rocket engine however small it may be and wondering if it will lift off without it. Macros are the first thing you may think of related to syntax change I am convinced that other areas benefit from the

Re: Searching for Regular Expressions in a file

Clojure's regex functions are built on top of Java's and Java's regex support is built on the CharSequence abstraction, not String as we normally think of them. You could adapt files to CharSequence without much trouble. I think this approach would keep the memory requirements to a minimum.
