I know this might be a little bit late in asking, because I've been
insanely busy too.

Say I know that I have a finite length of my tree-just 3 bytes-that I would
like to be cached. Instead of resolving the tree dynamically, I would like
there to be a contiguous array, but for each array entry, have some kind
special value-either a mapping that produces a value despite length, or a
concrete length limited pointer to result type.

[ <- 32 megabytes -> ]

An index into the radix tree can be performed by multiplying the first byte
by 2^16 (possibly minus one). Then a pointer to some dynamically managed
tree would suit our needs.

I calculate that a lookup, assuming that the tree is also shallow,
shouldn't take more than just a handful of instructions. I'm all about
speed in this scenario, and my use case requites that insertion consume as
few instructions as feasibly possible. Other operations aren't as important.
