One definition of a dynamic programming language [L1 ] proposes that any programming language that permits one to write applications that can change the structure of the program while it is running is a dynamic programming language.
[Be sure to mention David's "Dynamic Languages-ready for the next challenges" [L2 ].]
[ Dylan's "Dynamic Language", too. ]
escargo 9 Sep 2005 - There's a conference on Dynamic Languages, and not only is Tcl not in any of the programs, it's not even mentioned as a dynamic language, "like CLOS, Python, Self, Perl, php or Smalltalk." To me it seems like Tcl has a better right to be on that list than Self, since Tcl is probably more used. (There are probably more Tcl books than Self books as well.)
The conference is "DLS05 Dynamic Languages Symposium 2005 October 18, 2005, San Diego, California (co-located with OOPSLA'05)" [L3 ]
