I don't know how much is preserved in public archives, but I'm pointing you to the history so you can be aware of it when you make your decisions. </pre> Anthony Carrico 2012-01-11T08:03:50 http://comments.gmane.org/gmane.lisp.scheme.scheme48/2486 <pre>Hi all, I'm working on a scsh/s48 mailer demon.

Robert Ransom </pre> Robert Ransom 2011-12-31T03:28:10 http://comments.gmane.org/gmane.lisp.scheme.scheme48/2465 <pre>Hello, I don't understand the following Scheme behaviour: + '+ 1 + 1 #{Procedure 93 +} Why in the second interaction is the input '+' read as a procedure, but in the first as a symbol? I am very new to Scheme, so my apologies if this is a silly question. I'm trying to write an RPN interpreter in Scheme, and I thought I'd apply the procedure read from the input to a stack of operands, however, because of the first case, this method isn't robust. I don't understand how to 'unsymbolise' a symbol into its corresponding procedure. Maybe there is a better way to do this? Thanks for reading. </pre> Frank Lay 2011-12-17T23:52:41 http://comments.gmane.org/gmane.lisp.scheme.scheme48/2463 <pre>Hi, I tried to load the package defs from SSAX and it killed the macro expander. It appears that when BIND-ALIASES was switched to the new cenv representation it stopped including macro eval in the cenvs it generated, and SSAX touches it somehow, causing a (force #f). I put up a one-line patch to BIND-ALIASES so that it includes macro eval, as it did before, at https://bitbucket.org/wnoble/s48. However, I don't know exactly how SSAX triggers the access and didn't try too hard to come up with a simple macro to reproduce the faulty expansion. So, if someone would explain whether this is the correct fix, and why or why not, I would be grateful! And Mike: thanks for integrating my POSIX patch!

So, where before posix_kill took a PID record and a signal record, now it takes ints. I think the comments hinted towards something along these lines. This removes a good chunk of awkward (in my view) Scheme-written-in-C code. I put up a repo at bitbucket.org/wnoble/scheme48. I've only tested the code lightly, and thought lightly about the general approach, so I definitely would appreciate any suggestions!

I didn't found any reference to a profiler for Scheme48, although I've found references to a tracer. Is such profiling tool available? If so, where can I find any references to it?
