list topics for discussion and work for this OctConf

frequency of Octave releases
a new release from stable this OctConf. A new release from default in 4 weeks time. From now on, new releases every year in January with freeze before the Christmas holidays.
implementing String class
Matlab added double quote strings, which instantiate objects of their new String class. This behaves different from our double quote strings because it does not escape special characters. Being Matlab compatible will mean being backwards incompatible. Decided to first implement the String class and make the Octave internals handle it. Then we will worry about having the double quotes create them and decide about the escaping of characters.
scope of functions in script files
Matlab scripts can now include function definitions. However, these behave different from Octave scripts in two ways:
  1. functions defined in script files are locally scoped and will not be available after running the script
  2. functions in the script file can de defined in the script after the statements that use them while Octave requires them to be defined first.
jwe says that this behaviour should be simple to implement but will be backwards incompatible. Solution is to have the run function change and behave like Matlab does. Currently, the function source is the same as run. The function source will keep the old behaviour and can be used to source a file to import functions definitions into the global scope, as if the sourced file had been ran in the interpreter.
