A comment on my last question pointed out that I should avoid using style names that are already declared in TikZ, and I read the manual but it was somewhat vague on the side-effects of not doing this.
I've been looking at using some patterns to decorate the odd shape here and there, but the built-in patterns library seems a bit lacking in features. Using ideas from this question, it seems possible to override the built-in patterns by simply declaring your own with the same names. In theory, it'd still work, provided I set sensible defaults, but I'm uncertain as to how much more difficult it would be to debug code when things go wrong.
I don't really have time to come up with a MWE (assignment procrastination…) but has anyone tried something similar?
