[r6rs-discuss] Comparison procedures' number of arguments

[leppie]

Hi

I dont understand all this 'confusion'.

Example: monotonically increasing
(< 1)  should be #f or error, there is no increase, hence no comparison.

Logically, how can you ask:

- What is the difference?  (<)
- What is the difference between a frog? (< frog)

Neither of those make any sense. Logically you cannot compare less than 2
objects.

Like Ken mentioned earlier about the principle of least surprise. Why even
bother, when the meaning of a comparison operator changes depending on
arity?

A function/procedure should be simple and do one thing, it's function, not
functions.

My 2 cents

Cheers

leppie
