But they are such an important part of Perl (and unimportant parts of 
many other languages) that IMHO it makes sense to cover this.

I have seen Perl that extracts data using all manner of _index_
and _substr_ calls (guess what - it was written by  a C programmer).
Hardly a perlish way of doing things.
