I am a retired software developer. I retired at the end of 2003 and since then my computer programming activities have been for recreational purposes. I find Mathematica excellent for that.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 9. Although I have used Mathematica for all kinds of stuff, I use it mostly to pursue my long standing interest in Euclidean geometry, both in the classical Greek synthetic form and in the more modern analytical form.

comment Returning ancillary computation results from a function
What I would like to know why returning the full list {u, K, F} is not satisfactory. The user can always ignore the quantities he/she is not interested in. I would also like to know if recalculating EllipticDirichlet to get get the ancillary values is an issue. Like Szabolcs I am inclined to think implementing a simple option would be the quick and easy way; the option, if False (default), means the function returns u, but if True, the function returns {u, K, F}. But this is only one of six possibilities I can think of. An answer that discussed them all would be too long for this site.

comment Returning ancillary computation results from a function
@Szabolcs. In my opinion the OP has not given enough information concerning the design issues specific to his problem. Therefore, it seems to me that answers could only discuss general design patterns, which I feel is too broad a topic for this site. If the community feels differently, as it might, then the question will simply stay open.
