I'm trying to compile the following program:

short asd = 1;
short qwe = asd + asd;

Just an idea that popped into my head... Maybe I can use variant
for the input/output types? I haven't looked at it yet, so I'm
not sure what it does, or the performance costs.
I realized that because the final callback always gets called,
and the types of the intermediate steps may be differ
Just to be sure: whether or not an error is passed to a
callback, the
final callback is always called?
I mean, the last callback could also be called *only when
something
fails*, a bit like a default case in a switch, or an
error-handling
routine.
Yes, the final callback is always called, bu

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

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.

h_zet:
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.
