( #3333=superdoc: print w/replies, xml ) Need Help??
Re: And that's different from storing the result of a method (whether said method is a mutator or something else) in a variable, and call a method in said variable?

Yes, it is. Consider:  $people->bob->eye('green')->color; . As a reader, I assume that the call is returning an 'eye' object, not bob, again. But if eye's a mutator, then you might find out Bob's a brown man.

Re: You mean, it makes it difficult to change a method such that has a different return value? Well, that always is non-backwards compatible. Whether the user chains, or stores the result in a variable and does something with the variable, it's going to be non-backwards compatible. In most cases you can make it backwards compatible through Want.pm. But perhaps, this is an issue of my style...?

    [erix]: 1=0 is as short as TOP :)
    [erix]: "code of someone that died" -- kinda nice if your code stops working too
    [erix]: hard to implement, hmm
    [Corion]: erix: Well, they also seem to have changed the server, or some software, or whatever, and seem to be in the process of changing the DB schema from having the "username" as primary key to something else.
    [Corion]: Far too many things being done at once, or maybe only now has it become apparent that nobody knows that piece of software anymore
    [marto]: good morning all
    [Corion]: I consider having an abstract key as userid in your system good, because the "real" company-wide (or even larger) user id will likely not fit your criteria well
    [Corion]: A good morning marto!
