2. joiner uses an idiom that I've experimented with in the past: it
defines a local struct and returns it. As such, joiner's type is
impossible to express without auto. I find that idiom interesting for
many reasons, among which the simplest is that the code is terse,
compact, and doesn't pollute the namespace. I'm thinking we should do
the same for Appender - it doesn't make much sense to create an
Appender except by calling the appender() function.
Didn't know there was a solution to namespace pollution.
This one is a very nice idea, are you planning to use it in phobos in
general?
Retro, Stride... there should be many.
I plan to, albeit cautiously. Sometimes people would want e.g. to store
a member of that type in a class. They still can by saying
typeof(joiner(...)) but we don't want to make it awkward for them.
