Re: Why the need for an explicit new operator in Clojure?

Yes. But I guess I misunderstood the OP rereading the original post again. (Foo 42) vs. (instance? Foo 42) was my understanding (so no operator), but I guess it's more about (new Foo 42) vs. (Foo. 42). Am Freitag, 17. Mai 2013 07:48:19 UTC+2 schrieb tbc++: > > >>how do you distinguish between ac

Re: [ANN] getclojure.org

This is great, and will make clojure adoption wider. I hope its ranked higher in google results! Also, it would be great if it supports regular expressions like these: "->[a-zA-Z]*", "\*[a-z]\*", etc. as well. I was reading clojure code for a while, and I remembered "->Obj" to be a valid IFn, but

It is necessary - integer literals default to primitive long and I'm not sure if >= will inline if it doesn't have type information in scope. This bit of noise could probably be removed by improving type inference in the compiler. On Thu, May 16, 2013 at 3:09 PM, Pavel Prokopenko < pavel.a.prokop

Why the need for an explicit new operator in Clojure?

Hi. My understanding of Java (or jvm) is that you can not call a constructor without using a new operator. Why then (even with the suffix dot syntactic sugar notation) is the new operator required explicitly at all? What are the disadvantages to having it implicit? Thanks in advance amca --
