More accurately, it's Normal Order for macro and special form (actually
it's another fancy name of internal implemented macro), you may want to
take a look through the "application order vs normal order" part inside
SICP.

Here's a simple formula to understand practical Lazy:
Lazy = Normal + Updating

"Updating" is another fancy academic term for caching the evaluated value
to prevent redundant computation. Say, memorization.

I could be blamed for the over simplified explanation to say Normal Order
rather than more general term non-strict-evaluation, Normal Order is just
one of them, theoretically, but most useful.

In your case, there's no updating, so you shouldn't claim it "Lazy" in
computation. :-)
