My best guess is that enum arrays(except strings) and AA's are
instantiated every time you access them.
This is especially bad with loops.
Probably you want static or module level variable instead.
Module level AA's can't have compile time initializer, however
you can do initialization with module constructor instead.

But the input to the AA is static, it never changes. I thought D
would essentially treat it as a constant and compute it once?
(I'm only using the AA in one place but it is in another template
that is used twice. I can't imagine it would couldn't figure out
how to optimzie it, I'm feeding it a constant so...)
