You may read input delimited by a newline character (read-line), good thing is that immutable parts of the image can be shared

for reading from Unix input sources, and are quite fast.
** Better support for writing standalone scripts.
It's much easier to write standalone scripts now. Scripts can use
the new command-line switches to open dependent modules and load
dependent source code. Scripts can also be written in the Scheme 48
module language.
