Yes, both. It's good practice as well as being expedient.  As already
mentioned ParseArgs() is well-tested, elegant code which saves a developer
a ton of time.  At the same time its ability to handle positional or named
parameters and to allow parameters to be specified in any order allows
great flexibility on the part of users entering markup in pages (consider
how difficult it would be if you had to remember the exact order of each
parameter in a complex markup such as pagelist).
