I used a custom tag for a while, but that isn't much use in cfscript: <code><cf_struct _name="greek" first="alpha" seond="beta" third="gamma" [...] /></code> The custom tag simply loops through it's attributes struct and uses the _name attribute to create a struct of that name in the caller scope.

Nathan Dintenfass also mentioned that you could reduce the amount of typing using the foo.values[1] = 0; foo.values[2] = 5; syntax, but I would prefer a function based shortcut (if we can't have "CFON"). Where do you store these for easy access? App scope? Request scope? CFC? Good points.

It's not a true array--but some kind of hybrid struct/array. If you don't create the array by looping through the arguments array, some of the array functions won't work on it. I actually use both UDFs in my work as it does make it much easier to create arrays and structures. I'd really like to see these functions become native to CF. PS - The reason I don't like using the listToArray() is you can't use the delimiter in your values or it creates a problem. Having a true UDF that converts an list of arguments to an array is much more useful.
