The problem is that there's a general myth about fields, that that's all you're supposed to do, and that because it doesn't work, and to top it off uses pseudohashes, fields is bad.

My reason for not using fields has always been that in most of the books I was reading (Programming Perl 3rd Ed. and Damians book) would tell you about them and the 'Typed' my variables (and get my hopes up) and then tell you that they were built with pseudohashes which are an experimental feature and only to be used with caution, there might changes, etc. etc. etc. the usual warnings. Thus implying that use fields might also be a dangerous practice. I mean if it worked perfectly, more people would surely use this technique right? (at least that was my logic at the time).

So I guess my question to you (and everyone else) is, are fields really ready for real world usage? Can I get these benifits today, without the risk of using "experimental" features?
