How should I compare immutable ints to ensure that they are actually equal?
I was quite surprised to receive the following error message:
cbt2.d(732): Error: function object.Object.opEquals (Object o) is not
callable using argument types (immutable(int))
when I tried to assert that two values

I'll betcha this binding is going to be a pretty difficult task.
Simply using it might not be bad, can probably just use a few
extern(C) functions to take strings, but expanding it surely will
involve talking to complex C++ objects,

Yes i know it's horrible but is it possible to use global
variables spanning modules?
I need to capture a small amount of program data and deal with it
in termination signal handlers. The data will be captured from
various classes spread around different modules.

Hi!
I've been thinking about how alias template parameters work and
I'm really confused =)
It makes perfect sense for literals, names, etc. But what I can't
get is how does it work for delegates.
If I have a function

It's worth pointing out that Appender supports ~= so it's very
easy to swap it in, replacing builtin concatenation.
This works since 2.062 AFAIK. So is still quite new.

You'll want to use appender, from std.array:

phabricator looks pretty decent for code review, bug tracking etc. It was
created at facebook and is used by many other companies; it's actively
maintained and developed.
It could be a good replacement for bugzilla and other components.
