Re^2: "a bit of sugar "(HOP)

Thank you! +++++ Your progression of equivalent examples showed/taught me what was going on in that creation of an iterator.

example #1 was perfectly clear; that, I was familiar with.
#2 was still not a stretch.
#3 is where the "Ah Ha" moment came and the I realized that this was a 'labeling' technique.
#4 was just another layer of obsfication.

By the time I was reading the responses, I had gotten to the imap amd igrep examples in HOP, and it all came together.

This does make me wonder how many books one would have to read to find, and understand, all of these little special cases that exist within the language?

Thanks again..

It is always better to have seen your target for yourself, rather than depend upon someone else's description.

For my part, I won't live long enough to learn them all. Following Perl Monks and trying to understand and answer questions has taught me more than I learned in many years of using perl.	[reply]
