Yep.
If the thing following #' is a (lambda ...), then the #' is
redundant. We all know that is a function (it is harmless, though --
as far as redundant things can be considered harmless).
Things become more interesting if the thing coming after #'
is a symbol, like in #'car.
Then we all know we are talking about car's symbol-function.
This allows the human code readers and the compiler to be
smarter about the code.
