Amen! I've been using TeX for several years now and I've always wrote
\let in the wrong order (I really mean always, not a single time I wrote
it first in the correct order, until I told my self to always do the
reverse of what I'd consider first), Have I seen it written with an
equal sign, I'm sure I would never confuse it.
