This makes sense as they are code, not data. But what about the hash-quote or "function quote", i.e. the #' ? IIUC that tells the byte-compiler that something is a function, so the byte-compiler can examine if the function is defined at that point, and possibly even do some optimizations - but obviously the byte-compiler should already know that a lambda is a function! So #' with lambdas should be meaningless, right? But I suppose if they are meaningless, one might put them there just as well :) What's the policy from Emacs High Command? -- underground experts united http://user.it.uu.se/~embe8573
