some curiosity is that it seems that normal array can be 'directoried'
- turn in directory

say you got array

int tab[200];

  array is a directory that kas one key form 0=199 and one int value per 
key )jas its start adress and ocupies 200 ints of ram)

say you add a method to not revrite value under key but add one

  tab[22]:= 100
  tab[22]:= 120
  tab[22]:= 100

this can be done by just adding 3 64 bit values on a side
and this construct would be a mix of array and dict made
by list of key-values  the underlying implementation may
also be different liek array of seeds to heap based arrays too)

overally c needs such builtin dictionary a lot
