Why does this work? Or it is a bug?
When you play a little with this code it's easy to see _error_
that should not appear. So there's surely something worth
reporting as bug, but I don't yet know what.

I wish I could help with the development of D (either the
compiler or std library).
Is there a TODO list kept somewhere? Neither Phobos nor DMD have
an `issues` page on Github..
I found this http://wiki.dlang.org/Review_Queue but it's kind of
short.

Hi,
I just started learning D, and thought I'd throw myself in at the
deep end with some meta-programming, trying to write the
equivalent of the commonly used, async waterfall, and also,
because I'd like to use it...
If you aren't familiar with it, waterfall is a function that is

As a library solution I would do something like this:
Union!(int, string)[] elements;
elements ~= 1;
elements ~= hello;
Take a look at Algebraic in Phobos.

Ali, of course, is right. The only thing I'd add is for a
Windowsy programmer (unless you have cygwin installed) you
probably want something like cmd.exe instead of bash.

I mean, the last callback could also be called *only when
