Re: A drawback of the less-parentheses approach
Ah, reader macro! Thanks! Ignore next form (#_) The form following #_ is completely skipped by the reader. (This is a more complete removal than the *comment* <http://clojure.github.io/clojure/clojure.core-api.html#clojure.core/comment> macro which yields nil). (from *http://clojure.org/reader* <http://clojure.org/reader>) Conclusion: Don't use the *comment* <http://clojure.github.io/clojure/clojure.core-api.html#clojure.core/comment> macro. It makes runtime overhead. 2014년 6월 10일 화요일 오후 12시 22분 50초 UTC+9, guns 님의 말: > On Mon 9 Jun 2014 at 07:07:42PM -0700, Taegyoon Kim wrote: > > And you can't do this: > > user=> (let [x 1 (comment y 2)] x) > > Alex Miller (?) once pointed out that the #_ reader macro can be chained > like this: > > (let [x 1 #_#_y 2] x) > > Pretty nifty. > > guns > -- You received this message because you are subscribed to the Google Groups "Clojure" group.

A drawback of the less-parentheses approach
I once liked the Clojure's less-parentheses approach. Today I found that you can't utilize s-expression comments easily in Clojure. e.g. In (let [x 1 y 2] x) When you are about to comment out the "y 2" part, you have to move the cursor back and forth to insert new parentheses. And you can't do this: user=> (let [x 1 (comment y 2)] x) IllegalArgumentException let requires an even number of forms in binding vector in user:1 clojure.core/let (core.clj:4043) (comment) in Clojure is not really comment. It returns nil. http://clojuredocs.org/clojure_core/clojure.core/comment vs. You can do this in Racket: > (let ([x 1] #;[y 2]) x) 1 #; is s-expression comment in Racket. Parentheses are there to group logically related things together. -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: Clojure 1.5.0 bug (Java interop: Compiler.load(new StringReader(str));)
But then(putting RT.init()),
Compiler.load() works, but Console (stderr?) says
No need to call RT.init() anymore
So I think this problem should be fixed.
