<div dir="ltr"><div><div><div>I'm not sure that i remember the specific problem that you're referring to.<br><br></div>In CCL, many special variables (including those that affect the reader and printer have thread-local bindings.) I understand that this may not be what one wants in every case , but if your code is intentionally creating threads, having the value of e.g. *readtable* change in all threads becausee of something done in one thread can be undesirable and hard to track down and debug, and I think that there is at least a strong argument that CCL's behavior in this case is a reasonable default.<br><br></div>I don't like or use SLME and I don't know if its behavior has changed since the last time that I tried to, but when I did I found that the default behavior of editor commands which try to read a selection from an editor buffer and execute the expression that was read is to execute that expression in a newly created thread (with a new set of dynamic bindings) I can't think of any way in which this behavor can be callled reasonable.)<br><br></div>If I ever knew how to override this behavior, I've long since forgotten. I understand that many people might find my solution - avoiding SLIME - a bit drastic, but I I don't exactly miss SLIME.<br><br></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Mar 4, 2015 at 11:32 PM, Robert Cram <span dir="ltr"><<a href="mailto:robert@robertcramconstruction.com" target="_blank">robert@robertcramconstruction.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word">I realize that this is an old thread, but the issue just came up for me.
