There are multiple ways to implement DOTIMES complying with specification , but the most common would essentially execute something like this: (let ((fns ())) (let ((i 0)) (push #'(lambda () i) fns) (setf i (1+ i)) (push #'(lambda () i) fns) (setf i (1+ i)) (push #'(lambda () i) fns) (setf i (1+ i))...

4. the list (3 3 3) is undesired and is the effect of the closure created by the 'let over the iteration variable 'i. WHY?! The closures here are created by LAMBDA, which creates an anonymous function closing over its environment. LET is incidental and just holds the anonymous functions so that the...

LAMBDA is a macro that expands into (FUNCTION (LAMBDA ...)), so in CL they are equivalent. In some other contexts, like with many standard higher order functions, you can use both (FUNCTION function-name) (or #'function-name syntax) and (QUOTE function-name) (or 'function-name syntax), but they beh...

First problem is that your recursion doesn't have a proper base case. Your IF doesn't have an else branch, so the result variable is returned as is, which is affected only by the first PUSH. This can actually be seen by indentation. Second problem is that you are trying to use PUSH in the first plac...

I have moved the topic to Emacs Lisp section.

First, LISP is not a language, it is a family of languages. Common Lisp is one of the languages of this family, and I assume you are asking about that since this is a CL subforum, but you should be clear about the difference when writing. The file chapter in Practical Common Lisp explains this. You ...

I'm curious why this is - is it considered an advanced topic? Technically deficient? Not useful in practice? In my experience at least, DEFTYPE is not really that useful in practice, other than defining short names for complex array types and the like. The standard does not specify any type inferen...

I have a strong feeling that this is not an use case anyone writing the standard thought of. I would say strictly speaking no, since the only requirement is "as if read had been called on an input stream containing those same characters. ", without requiring that the stream is fresh, altho...

I can't believe you can't predict the order of such a computer language function output!! In this context "unpredictable" means that it depends on the implementation and the state of the system as whole, which means that even if you can predict the order in some circumstances, programs de...

Using macros seems to me like a premature optimization for this case. Although I know very little about specifics of elliptical curve algorithms, I doubt the cost of algorithm dispatch is that significant. You should probably write a version just using functions first.
