Holy crap: JVM has coroutine/continuation/fiber etc.

Posted by forax on November 19, 2009 at 4:01 PM PST

Lite closure in JDK7

Posted by forax on November 18, 2009 at 8:58 AM PST

It seems that "lite" closure will be in JDK7.
I really don't care about the surface syntax but I hope that the runtime of such closure will be on top of JSR 292 method handle.

The tales of the four Fibonacci's

Let me introduce a new language named pseudo (Why this name ?

DLR Expression Tree like in Java

Two months ago, I was discussing with a friend about
dynamic languages and JSR 292 when he mentions
DLR Expression Trees.
At that time, I had a vague memory,
mostly because I was under the effect of a
persisting jet lag, when I attend the talk of Mads Torgersen
about it at last year JV

I've just released the first version 1.0.1
