Not only is Clojure "a reasonably sane Lisp", it's a practical language that feels designed (because it is) using "power trough simplicity", decomposition, decompletion.

This frees up an enormous number of brain cycles to design the upper layers.

It embraces it's host (JVM, JavaScript) which enables tremendous reach and code-reuse; at the same time it fixes most WATs and subtler pitfalls (by using immutable, persistent data (structures) by default).

If only the problems of slow startup and unfriendly error messages could be solved - it would be like a dream coming true.

I think the spec library that they're putting together right now might be able to solve the error messages. What I'm waiting for is to be able to hit something like dot in my ide and see a list of suggestions, I'm not sure if spec can be leveraged to that extent.

Completing the first half of a symbol that I've been typing already works reasonably well with Cursive.

Matching up specced postconditions with preconditions might work, but I'm not sure how well.
