I'm want to define a specialization of `append()` that takes

Have anybody already implemented this?
If not, I'm specifically interested in how to most conveniently
infer the length (as an enum) of the returned static array from
the `.length`s of inputs (which of course must be enum-values
too).
I just realized that I can use `std.meta.staticMap` to get the
lengths but I still need to reduce them and there is no variant
of `reduce` in `std.meta`. Why? Hasn't it been written yet?
I know I can always write yet another recursive CT-function, say
`SumOfLengths`, but I thought I'd try to reuse `std.meta` this
time. :)
