Seed7 - The extensible programming language

Seed7 is a general purpose programming language. It is a
higher level language compared to Ada, C++ and Java. In
Seed7 new statements and operators can be declared easily.
Functions with type results and type parameters are more
elegant than a template or generics concept. Object
orientation is used when it brings advantages and not in
places when other solutions are more obvious. Although
Seed7 contains several concepts of other programming
languages it is generally not considered as a direct
descendant of any other programming language.

Changes:
- The interpreter (hi) and the compiler (comp.sd7) were
  improved such that the actions STR_CPY, STR_APPEND,
  ARR_CPY, ARR_APPEND and SET_CPY work correctly when
  source and destination are identical.
- The compiler was improved to use the functions
  stringLiteral, bigIntegerLiteral and bitsetLiteral to
  write occurrences of string, bigInteger and bitset
  literals to the generated C program.
- The functions arrHead, arrHeadTemp, arrRange,
  arrRangeTemp, arrTail and arrTailTemp in the file
  "arr_rtl.c" were added or improved to avoid unnecessary
  copies of arrays in compiled programs.
- The functions free_helem, free_hash, create_helem,
  create_hash and copy_hash in the files "hshlib.c" and
  "hsh_rtl.c" were improved to increase the speed of the
  actions HSH_CPY and HSH_CREATE in interpreted and
  compiled programs.
- The function chrCLit was added to the file "chr_rtl.c"
  to support the action CHR_CLIT in the interpreter and
  in the compiler.
- The function chkPower in the file "chkbig.sd7" was
  improved.
- The function check_assign was added to the file
  "chkset.sd7".
- The functions check_string_append and check_string_assign
  in the file "chkstr.sd7" were added or improved.
- Several improvements were done to avoid that old memory
  areas were accessed after realloc() was called.
- The function bigLShiftOne was added to "big_rtl.c" and
  "big_gmp.c" to allow faster computation of powers of two
  in compiled and interpreted programs.
- The functions bigIPowN, bigIPow1 and bigIPow in
  "big_rtl.c" were added or improved.
- The function drwOpenSubWindow in "drw_x11.c" was changed
  to omit the creation of a graphic context.
- The function filWrite in "fil_rtl.c" was improved.
- The functions strAppend, strAppendTemp, strHead and
  strHeadTemp in "str_rtl.c" were added or improved.
- A possible memory leak in 'while' and 'repeat' loops of
  compiled programs, which can occur when the conditional
  expression produces temporary values in the heap, was
  closed.
- The handling of the action STR_APPEND in the compiler
  was improved to use strPush when possible.
- The handling of bigInteger expressions with constants in
  the compiler was improved.
- The compiler was improved to support the actions
  CHR_CLIT, CMD_FILETYPE_SL and CMD_SYMLINK.
