Yes, those are very much elements that I had in mind and good confirmation that my initial ideas aren't too far off the mark.

CPAN will get coverage, but most of these people are accustomed to using the Boost library which provides some inoculation against the "ain't written here" syndrome that often mitigates against using resources like CPAN. Probably I'll use Getopt::Long as an example module - something that's pretty much immediately useful and easy to understand and use.

Using for in for (;;), for (x .. y) and for (@array) variants to compare and contrast the different usage modes for for loops was definitely one item on the list of topics to cover.

The power of hashes is indeed another "must cover" topic.
