Funnily enough, I have only just downloaded the full and unabridged Cygwin 
onto my Win XP machine. I actually /physically/ felt a sense of relief and 
reduced tension as I did this, knowing that I now have a real development 
environment available, rather than Windows, which just isn't.

It's hard to explain, to the outside world, how important the deep sense of 
personal empowerment (hehe) is that comes from a having proper development 
environment, to a hardwired programmer. However, I have got that sense much 
stronger from environments such as Smalltalk and even the likes of Python 
and Ruby than I ever have from Unix (and its shells).

But my point is that Unix, in its entire design philosophy, runs counter to 
the design philosophy of Ada. Ada has been carefully designed to help 
protect people against accidentally shooting themselves in the foot, 
whereas Unix seems to have wilfully designed it to make this as easy as 
possible. What excuse is there for that, other than sheer mischief?

So why doesn't rm come with the -i behaviour as default? There could always 
be a -f switch to switch it off.

No, I'll bet that my fellow student has avoided ever using Unix again, and 
I couldn't blame her.
