Because it forces the interpreter to check for the presence of
a `declare' every time it sees a `let', even though it will only find
one once per century or so.
It's an OK design for a language where there's always going to be
a pre-processing of some sort before evaluation but for Emacs's pure
naive interpreter it's inconvenient.
