I think using argumentCollection is a completely valid way of doing
things. I use it all the time. Why write everything out when you can
do things like argumentCollection=form or argumentCollection=url?
You'll also find it in my code generator whereby I turn a query row
into a struct and init a new bean using argumentCollection. Suffice it
to say I use it wherever I can. I think it does a couple of beneficial
things, the primary being that when your arguments change you don't
need to go around updating your function calls. The second is, it
makes handling empty values easier. For instance, let's say you were
passing a full name you might say
user.init(firstName=firstName,mi=mi,lastName=lastName). However, how
do you handle the middle initial (mi) if it isn't defined because it
is not required. You could pass an empty string and code your function
to check for that, or you could just use argumentCollection. This is
actually a poor example, since it works better for numeric and other
types where, if you type check your arguments as you should, you can't
use empty string as a null equivalent....but I think you get my drift.
Absolutely, I use it for similar reasons as well. But, I don't know
that if I was hand-coding things, I would use it quite "so much." A
generator or framework is one thing, but daily use and having to think
about it is another. It may makes things easy in the short run, but I
would think that having to go back over some code a year after you wrote
it (or someone being new to it altogether) would be difficult if the
code documents itself like that...

Q: If you have a ton of arguments, is using
ArgumentCollection the best practice?
I wouldn't go so far as to say it's a best practice or it's not, but my
personal preference is only to use ArgumentCollection when I might have an
unknown number of arguments.
