CORE LANGUAGE FEATURES

CORE COMMANDS

- [onleave] command, executing something as soon as the current procedure
  returns. With no arguments it returns the script set, with one appends
  the onleave script. There should be a way to reset.

OTHER COMMANDS NOT IN TCL BUT THAT SHOULD BE IN JIM

- Set commands: [lunion], [lintersect], and [ldifference]

EXTENSIONS

- OOP system
- Cryptography: hash functions, block ciphers, strim ciphers, PRNGs.
- Tuplespace extension (http://wiki.tcl.tk/3947) (using sqlite as backend)
- Zlib
- Gdlib
- CGI (interface compatible with ncgi, but possibly written in C for speed)

SPEED OPTIMIZATIONS

- Experiment with better ways to do literal sharing.

  * Currently literal sharing is completely removed. Can it be made
    efficient? What is the cost vs. benefit?

- Organize the 'script' object so that a single data structure is
  used for a full command, and interpolation is done using an
  'interpolation token type' like JIM_TT_VAR and so on.
  This way there is no need to run the array of integer objects
  with the command structure. Also should help for better cache usage.

IMPLEMENTATION ISSUES

- Objects lazy free.

- Rewrite all the commands accepting a set of options to use Jim_GetEnum().

- Every time an extension is loaded Jim should put the dlopen() (or win32
  equivalent) handle in a list inside the interpreter structure. When
  the interpreter is freed all this handles should be closed with dlclose().

- *AssocData() function should allow to specify a delProc C function like
  in the Tcl API. When the interpreter is destroyed all the delProc functions
  should be called to free the memory before to free the interpreter.

REFERENCES SYSTEM

- Unify ref/getref/setref/collect/finalize under an unique [ref] command.
- Add a 'call' attribute to references in order to call a given procedure
  if the name of a reference is used as command name.

RANDOM THINGS TO DO ASAP

- .jimrc loading, using the ENV variable
