I guess you are saying to introduce lots of small building blocks and see what she can build from them. It sounds good and I think I’ll try to do that. I wasn’t planning on keeping the difficult stuff for last but rather to introduce it when it appears natural. s/// in its simple forms shouldn’t be too hard to understand and the more complex use can be built up gradually as the need arises. Simple text processing should be introduced from the start. I always found this to be hard in the languages that I first learned – because they didn’t have the features that make it easy.

[moritz]: seems there's a size limit for hostenum, and the error message just sucks
[vrk]: None, other than the location of the error: auto/NetAddr/IP/ _splitref.al
[vrk]: Aha, there's a reference to "bug report 82719" in NetAddr/IP.pm's sub _splitref.
[moritz]: wow, that's their idea of an "improved error message"
[moritz]: how about "This network is too large to enumerate all host addresses." or so?
[vrk]: Well, there's a call to notcontiguous() before the error, whose description is "counts the bit positions remaining in the mask when the rightmost '0's are removed"
[vrk]: Clear as mud!
