Object is the base class of all classes. Nothing which is not a
I have problem with "Object"
for example this doesn't compile:

Reserving space for appending does not make that space immutable, yet.
As far as the runtime is concerned, that space is

Just because it's immutable doesn't mean that it doesn't need to exist at
runtime. All immutable means is that you can't change it. It coul

Also, std.string.repeat has been scheduled for deprecation. You should use
std.array.replicate instead. It does the same thing but for all arrays
instead
of just strings.

I've got 2.053 and it works for me.

Your code fail for me with:

Because the mixin is evaluated at compile time. This means that

The runtime tries its best to avoid allocating a new string on each
append. Please read the manual on appending, and

This works for me, DMD 2.053:

Apparently std.string.format() is not implemented / does not compile! :(
Is there any sort of replacement?
Something which works like writefln() but output a string!

You have to take a look at the asm produced by the compiler to be sure what its
optimizations have done.

Do you know if in Phobos there is already a way to format a number with
thousands separators (a point, comma o underscore)?
