I mean that most programs don't work that way - at least not the ones that 
I've used. Some _do_ work that way, but in my experience, it's abnormal. I do 
find it interesting though that all of the examples that you give are 
compilers or related to compilers. Assuming that they're the prime examples of 
programs that work that way, I wonder if there's something particular about 
compilers which makes it so that they don't follow the more general trend (the 
overabundance of flags that they have perhaps?). But maybe my experience in 
the matter is just lopsided.
