Have you any tips for using D when you need fast string
concatenation? I regularly use code like this:
foreach (i, range)
{
foo ~= bar;

or:
foo = foo ~ bar ~ baz ~ qux;
I've used std.string.format(...) in some instances which sped
things up which surprised me.
Are there faster ways of appending strings?
Regardless of whether you end up using lots of ~=, or Appender
(possibly with formattedWrite), using reserve never hurts.
It's worth pointing out that Appender supports ~= so it's very
easy to swap it in, replacing builtin concatenation.
