To Do:

 * optimize fcode words - use native fcode implementation where possible.
   Currently all fcode words are written in C. This is fast but memory
   consuming.
 
 * implement missing fcode words. about 150 of 360 words are still missing.
 
 * reduce memory consumption
   maybe reorganize dictionary structure. Only keep defined words in
   memory/rom?
 
 * feval's support for  instances, packages and properties is untested.
   This needs a lot of fixing I assume
   
 * calculate fcode header checksum and bail out, if wrong.
   check for valid header before executing fcode program.
   
 * get rid of fixed buffers for fcode function creation or
   adopt buffer sizes from the spec
 
 * Check specs and implement compilation state properly for
   parsing of loops and functions
