Try as I might, I can't purge these anachronisms; so here are `car' to
`cr' in all their glory:

This implementation uses a Kleene-closure around the alphabet {a, d}
to generate the names; and a macro to define them:

Trampoline and recur are a poor man's tail-call-optimi
This talk of "Scheme macros" is a little weird: are we talking syntax-case,
explicit-renaming, or unhygienic defmacro? Scheme has them all.
There are also implementation-specific mechanisms for writing reader macros:
what's left?

Thanks, Evan; I had a use-case where the truthiness of nil would have
forced me out of `let-else.' This new predicate-abstraction is
beautiful.

Despite Brian Carpenter's warning about torches and pitchforks [1],
I've decided to release a reader-macros package; may Zeus forgive me
for opening this pithos:

Here's a trivial example where we implement a reverse-string reader:

Whoops: that's Brian Carper, not Carpenter.

That's a little idiosyncrasy of mine: I've been chastised for it in
the past; maybe `lambda' would be more readable?

Exactly: `λ' and `defλ' are just vanilla macros that shadow `fn'
Scheme, for instance, obeys the Law of Macro-Parsimony: "don't use
defmacro," namely, "where defn will suffice;" Clojure, on the other
hand, is macro-liberal.
In other words, everyone seems to prefer e.g. `(defmacro foo [vars &
body] `(do ... ~@body))' where `(defn foo [vars thunk] ... (thunk))' w
all things.

SICP-forged neural pathways, basically; I'll end up writing e.g.:
(defn with-input-from-file [file thunk] ...)
only to censor myself: "shit, we don't do thunks."
At that point, I'll bust out `defmacro' with relucta

It sounds
Since square brackets have been usurped by vectors, angle brackets
could be used to approximate M-expressions.
