It's not just a matter of coalescing it with other similar lists, the file compiler can do other things, like putting it in read-only memory...but the REPL can never do such things (Emphasis mine.) I don't believe the spec says that. See below. so in fact you can modify "literals"; it's p...

Presumably you're supposed to be typing this at the REPL, so there is no problem (the results are perfectly well defined as long as you don't file-compile it). Well... “The consequences are undefined if literal objects (including quoted objects) are destructively modified.” ( CLHS, Special Oper...

Also note that, while I don't know what it is you're trying to accomplish, and higher-order macrology (i.e., macro-generating macros) is generally quite fine and sometimes necessary, the particular case you cited can easily be handled without this kind of complexity, since object-mult doesn't seem t...

This made things run smoothly, but I'd have a nagging feeling about some smart compiler noticing the subterfuge ... You may want to declare the variable SPECIAL, which will at least prevent the compiler from determining statically that the declared variable is not needed. In that case, you can also...

You could temporarily put the wrapper somewhere the GC will notice it, such as a multiset (FSet calls this a “bag”) referenced by some global variable, and remove it again at the end of the context. Of course, in case your code is multi-threaded, you will have to make sure that access to the dat...

Are there conventions for dot files (I saw reference to a ".clc" but no info on what should be put therein)? The directory ~/.clc/systems/ is where CLC looks for .asd files. (Note that you must symlink them there from their original directories, not copy them.) In fact, I've been using th...

For Scheme, I nominate schemers.org and the Community Scheme Wiki.

(let ((a 1) (b 2)) (destructuring-bind (#:a1 #:b2) '(4 5) (setf b #:b2 a #:a1))) Note that this piece of textual representation of code alone doesn't say much: The printed representation of uninterned symbols is ambiguous. In the above code, for instance, the two occurrences of #:a1 may or may not ...

Scheme calls it pair?. Other than that, it should work the same way.
