# Why talk about clojure?

- close to ruby as per "change-anything" at runtime 
							- but JVM final + immutable
							- alter-var-root (incl. clojure.core/)
							- see [technomancy/robert-hooke](https://github.com/technomancy/robert-hooke) lib
						- written in a clear high-level language
						- *relatively* performant
							- [clojure-goes-fast](http://clojure-goes-fast.com/)
						- source is quite educationable and *ideomatic*
						- builds relatively fast
					
						note:
						- verbosity of java is rather good
						- who's read tonsky article - please go learn rust
						- I'm keen to say that clj is the most flexible language (somewhere near ruby) I ever saw
						- doesn't require to think about memry management and c-extensions byte-level stuff
						- as the parser is basically a depth-first tree walk - a good (just as any lisp)
						- ruby parser is literally crazy, but clojure has first class persisstent ds impl
						- extensively uses RT and structures in source

What if you tired to shift

That was easy...

Go deeper

you know, we have +1 problem more

know your tools
change and adapt your tools for yourself
don't fork clojure for your production
unless you know what you're doing
be happy
