That looks very confusing. The left-hand side looks like a
slice, which I can append elements to but its type is a static
array?

That is intended (but can be discussed of course). It was often
desired to write int[$] arr = [1, 2, 3]; to auto-determine the
dimension. And my change does something like that: if you
assign a static array to a slice, the dimension is
auto-determined and the type is adapted.
I agree with Ali. arr2 says it's a dynamic array but it's not.
This could easily lead to errors worse than the class caused by
implicit conversions (what's worse than explicitly saying you
want an x but getting a y instead?). `int[$]` for this purpose
would be acceptable, however. I actually like that idea,
personally.
