Reference examples can be misleading to a new user

[jaderoca]

I didn't think this was enough to call a bug, but if you like, I can compose a formal bug report for "Issues"

From what I can tell, this might be a general issue, but I'll confine myself to max' and min`.

The examples as given work just fine, but as soon as I try to use a variable, I get word-based comparisons instead of value-based comparisons. Using [ ] instead of '{ }' not only solves the problem, but would also work fine for the examples. If there is a use for comparing the 'size' of words as words rather than the values they represent, perhaps that could be an additional example.

As I gain experience, these kinds of things become more obvious to me, but I still get caught off guard often enough to be annoying.
