Hey, I've got a few questions if anybody's got a minute. I'm trying to wrap my head around the threading situation in D. So far, things seem to be working as expected, but I want to verify my solutions. 1) Are the following two snippets exactly equivalent(not just in observable behaviour)?

What is the corect behavour for lazy in foreach variadic template

Take the following code for example module test; import std.stdio; void test(T...)(lazy T args) { foreach(arg;args) //bar is invoked here { writeln("about to process arg"); writefln("processing arg %s",arg); //but it should be invoked here, right? } }
