And we might as well say *why* it should be killed: When you quote
a lambda form, the code simply creates a *list* (whose car is `lambda'
etc.) when it is evaluated. That list can then be interpreted as a
function (or not, depending on the context - it is just a list).
But if you do not quote, then the lambda form is understood
immediately as being a *function*. And that means that occurrences
of that function can be byte-compiled etc.
