4. What you can learn
How REBOL can return a block of filenames by using load on a directory specification. In this example, load %./.
The REBOL size? function returns the length of a file. Note there are complexities to this in real life, as operating system filesystems usually have allocations that don't match actual file sizes. But that is a more advanced topic.
5. What can break
By default, REBOL security settings do not allow directory reads for most directories. Modified versions of %sizedir.r may cause a security question, unless you start up REBOL with the -s option.
