I prefer Guido's formulation (which, naturally, I can't find a direct
quote for right now): if you expect that a boolean argument is only
going to take *literal* True or False, then it should be split into
two functions.
So rather than three boolean arguments, would you have eight functions?
If there's genuinely a need for that functionality, yes.
So you want a function such as drawtext(s, bold=true, italic=false,
underline=true) to be split into:
drawtext(s)
drawtextb(s)
drawtexti(s)
drawtextu(s)
drawtextbi(s)
drawtextbu(s)
drawtextiu(s)
drawtextbiu(s)
Which of course is going to be fun if the bold/italic/underline values are
not constants; instead of writing:
drawtext(s,b,i,u)
you have to say:
if b==0 and i==0 and u==0:
drawtext(s)
elif b==1 and i==0 and u==0:
drawtextb(s)
and so on. With half-a-dozen or more booleans, this becomes completely
impractical.
