D adds a very handy feature that allows you to check for a range of
values in a single case. Is there a particular reason that the syntax
"case : .. case :" is used instead of treating the case
statement similarly to an array slice, e.g. "case .. :"?
For example:
import std.stdio;

While working on a library built for high efficiency, avoiding
unnecessary copies of structs became an issue. I had assumed
that `in` was doing this, but a bit of experimentation revealed
that it does not. However, `ref in` works great.
My question is, should `in` by default also imply `ref`
I encountered a very unexpected error when working on a project.
It seems that the Appender and RefAppender structs created from
the std.array.appender() method are sensitive to the mere
presence of a method called "init()" on the element type of the
array.
Here is a minimal example:

I've been experimenting with code that uses std.functional :
binaryFun and unaryFun, but I have found that using these methods
makes it impossible to add function attributes like @safe, @nogc,
pure, and nothrow, because no guarantee can be made about the
functions created via a stream. For exa
