Yes, this is similar to small array optimization, but this variant of the idea
allows you to tune how much space you want to save locally.

Beside staticLen, this InlinedArray also optionally takes the Tlen type. If you
are using something very small, like ubytes or chars or shorts, and you want to
pack as many of them as possible in the local static array, you are allowed to
define Tlen as ubyte (or ushort) instead of uint or size_t. So
InlinedArray!(int,1) takes 12 bytes and stores up to 11 ubytes/chars.
