Update:
    - string concatenation has been moved to builtin as part of
      strcat(3) emulation.
    - new <<+ here-document
    - more ${var|...} operators.

Update:
    - all builtins are now dynamically loadable.  Can also be statically
      linked, as one-in-one binary.
    - stack/queue operations (ie. pop, push, append, swap, rotate, ...)
      on positional parameters and arrays.
    - Expat XML parser interface
    - x-y character plot
