* Key filtering on dictionaries (hooks for key comparison and hashing, on
  the elastiC side).

* General iteration support.

* Install dynamically loadable C modules in ${libdir}/elastic-x.y.z
  instead of ${libdir}/elastic

* Eliminate SetLineOP moving the line number information to a separate
  data structure, field of EcCompiled. This could be a list (byte code
  index, line number). Could (should) be part of debugging information.

* Switch to more simple hashing scheme with doubling and simple linear
  searching.

* Add array.concat(), ...

* Integrate GNU libltdl & use a machine independent shared module layer.

* Adapt byacc || byson || zyacc to code re-entrancy and/or elastiC output.

* Add Bytecode Description Blocks (& Package Description Blocks) to
  describe variables, line numbers, ... in code.

* Add object serialization framework (with optional filtering).

* First class type ?

* Method support for every type ?
  Subclassable basic types ?

* Every type an instance ?

Switch to 'configure' dependent basic types  - DONE

! Evaluate the possibility of incorporating nargs into stack
  structure.  - DONE

Finish hash table expansion (use next prime calculation)

Change tc_compiled to tc_bytecode
Change object to instance (tc_object -> tc_instance, ...)

Evaluate the possibility of using bound functions & methods.

Add license file. Add --license (-L) option to programs: ec, ecc, ecdump,
ecgtk, ...

Add -l ELASTICPATH to ec, ecc, ecdump.

Add construct:
     for i in sequence where condition

Add expression 'in' (ala Python)  - DONE

Add function pointers "getitem", "setitem", "promote" to user data-types   - DONE

Implement generic math operations   - DONE

Add math.*                          - DONE

Handle circular reference problem in printing, passivating, ... (hash table)

Add 'switch', ++, --, +=, -=, *=, ... etc. - DONE, still missing 'switch'

Add 'break' in exception handlers (jumping to the end) ?

Add 'finally' block

Add 'precodition', 'postcondition', 'invariant'('assert'), 'doc'

Add linux kernel module for elastiC executables !!!

Add generic construction
