Actually, while I'm not exactly in love with them, it's ok for now. My
problem with the above is that, if we are talking about many variables
(which I run into more often than I'd like), the D(x=.., y=....) call
becomes ridiculously long, error prone and plain ugly. I think it's ugly
even for a few variables, but at least it's easy to get it right if it's
short.
Any other approaches/ideas/comments?
The fact that in such a cleanly object oriented language, there is no easy
way of accessing an object's member data for string interpolation (without
making zillions of temporary locals as above) strikes me as a _big_ wart.
I'm known to be a rabid python fan, yet I still can't get over this thing.
For some reason, it seems to bother me a lot more than most other python
users ;)
Cheers,
f.
