By spooky, we mean explicitly using the `~` operator or `length 
=`? I like the idea of reducing types because it avoids function 
coloring. For example, when you accept `const(char)[]` you accept 
a lot of different things. Golang has also something similar with 
slices.

`T[>..256]` could be added to the standard library. It's a static 
array with a dynamic length field, and maybe a shrink left bool 
if you want to be cool like a Goose. Just having the dynamic 
length is fine for my use cases.
