I bought the book and am trying to patiently learn this

D1/D2/Phobos/Tango and
not just really poor unvetted tutorials. It would really be
helpful if
those providing references, code snippets, tutorials, etc
clearly
identify the context (i.e D1/D2/Phobos/Tango). I just think
it would
help accelerate the spread and acceptance of this language if
more of
the code worked as listed.
If people are out cruising the web and download a fresh copy
of D with
excitement (about a cleaned-up, updated c-type systems
language) and
then the first several things don't compile w/o errors,
they're going to
move on.
Thanks so much to all who provide references, tutorials, etc!
It is
great service in helping others learn. I hope this is seen as
constructive criticism for that is what it is.
Hi !
It's simple: use D2, and forget about Tango.
D1 is deprecated and its maintainance will be stopped by the
end of the
year. Noone should be starting with D1 now.
You can start here:

I cleaned up this page a little bit, I hope this helps.
I tried one "file open" example from this site and one from
another site and neither compiled w/o errors. I thought perhaps
I had copied some code that might have been related to a specific
version of D. I was just commenting that for people who are
supplying exmaples/tutorials it would help if they specified more
clearly what version/genre of D their code sample works with. I
have no opinion on the Phobos/Tango or deprecated
features/version stuff. I just think it would help the
acceptance of the language if stuff compiled as listed.
As for the example from this site under std.stdio; it should
compile. It's a simple program. This is the mother site.
A member helped me realize that it needs "import std.stdio;"
// test.d
void main(string args[])
{
auto f = File("test.txt", "w"); // open for writing
f.write("Hello");
if (args.length > 1)
{
auto g = f; // now g and f write to the same file
// internal reference count is 2
g.write(", ", args[1]);
// g exits scope, reference count decreases to 1
}
f.writeln("!");
// f exits scope, reference count falls to zero,
// underlying FILE* is closed.
}
