CAS command question

So left(x<2) returning 2 is *definitively not* a bug.

ad nauseum:

Of course it's not impossible to make left and right return what you would like, but that require reviewing everything in the CAS that handle inequations and certainly rewrite parts, a long and bugprone task that would probably impact normal users. Therefore I won't do it

re-Quote (Dale):
Well, now ... Parisse' post is completely understandable and adequately addresses my original concern!

There's a huge difference between the consequences of changing the existing behavior, and CAS systems not being able to do it.

CAS left() and right() commands are not well suited for general use, and for good reason.

This is the point where it ends, I thank you: (seventeen years)! How quickly time flies! And we move on. (I welcome you to visit America! In America we drive on the right hand side of the road. if you drive on our roads, (Lord, please guide him), I hope you don't evaluate like your CAS does... .)
