that's an impressive set of changes for a minor release! :o) is there a paper that describes the underlying implementation (with the new stackless stuff)?

- anoved 14y agoI don't know of a paper, but on the Tcl wiki there is some discussion of the "non-recursive evaluation" (NRE) engine that enables these features [1]. More formal descriptions of the new coroutine [2] and tailcall [3] commands are listed, among others, here [4]. 1. http://wiki.tcl.tk/37253#pagetocbefb5a57 http://wiki.tcl.tk/37253#pagetocbefb5a57 2. http://www.tcl.tk/cgi-bin/tct/tip/328 http://www.tcl.tk/cgi-bin/tct/tip/328 3. http://www.tcl.tk/cgi-bin/tct/tip/327 http://www.tcl.tk/cgi-bin/tct/tip/327 4. http://wiki.tcl.tk/21276 http://wiki.tcl.tk/21276 Update: more details on the NRE implementation are available here [5] at the contributing author's site; anonymous login required. 5. http://msofer.com:8080/wiki?name=NRE http://msofer.com:8080/wiki?name=NRE
- kevinwalzer 14y agoTcl's "minor" or point releases are bigger than most languages'. 8.6 has been in development for about four years. 8.5 was also in development at least that long. Contrast Python, which does a point release every 18 months or so.
