I find the former to be easier to understand. Also, it allows
one to have position independence in calling parameters -- I don't
have to remember to put in all the parameters in the same order
wherever I call the function. Also, I do not have to send in 0 or
NULL parameters -- I only set the non-zero parameters at each
invocation. I also like the fact that I can add parameters to the
function and not to have to change all invocations. Also, I sometimes
add new parameters while writing the caller; I like the fact that I
can still test and the new parameters are ignored (this last is
merely personal preference, I code in a mixture of top down and
bottom up methodologies, and sometimes parameters/functionality
changes on the fly).
Hmm. You note that I can (and do) check required
parameters. You may wish to look at pkg-order, one of the more
complex Perl programs I have written.
