=begin
StringIO
Pseudo ((IO)) class from/to ((String)).
This library is based on MoonWolf version written in Ruby. Thanks a lot.
Differences to ((IO))
- not implemented: ((fcntl)), ((reopen)).
- ((fileno)) returns nil.
- ((pos=)) returns new position, not 0.
- ((ungetc)) does nothing at start of the string.
