CORE LANGUAGE FEATURES

- Proc default arguments
- Traces
- Closures, exported as a command that can set/get/unset elements
  from a dictionary associated with the current procedure.
  The [closure] command should allow to perform this operations,
  and to access the closure of a procedure from another one.

CORE COMMANDS

- All the missing standard core commands not related to I/O, namespaces, ...
- [tail] command for programmer-driven tail recursion optimization
- The current [expr] needs a lot of work, expecially operators && and ||
  are not lazy. Math functions are not present but probably will never
  be added as expr functions, but as Tcl commands, like [sin], [cos] and
  so on.
- 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.
- List commands to add: [lreverse], [squeeze]
- Set commands: [lunion], [lintersect], and [ldifference]

COMMANDS NOT IN TCL BUT THAT SHOULD BE IN JIM

- commands to operate on sets (that are lists semantically).

EXTENSIONS

- Regexp extension
- OOP system (this will possibly part of the core)

SPEED OPTIMIZATIONS

- Find a way to avoid interpolation/reparsing in "foo($bar)" tokens.
  See the "sieve" and "ary" bench performances, result of this problem.
  (to compare with sieve_dict is also useful.)
- Many other possible things, including better literal sharing.

IMPLEMENTATION ISSUES

- Objects lazy free.
- [split $string {}] should generate a list with Jim_Obj of chars shared.
- [closure] command to set/get procedures-specific closure variables.
- Rewrite all the commands accepting a set of options to use Jim_GetEnum().

ERROR MESSAGES

- Display the procedure relative file number where the error happened.
  Like:

  In procedure 'check' line 11, called at file "test.tcl", line 1024

  instead of just:

  In procedure 'check' called at file "test.tcl", line 1024

REFERENCES SYSTEM

- All ok for now, already done things deleted from the TODO list.

API FUNCTIONS TO EXPORT

- Jim_FormatString()


RANDOM THINGS TO DO ASAP

- .jimrc loading, using the ENV variable
- [source]
