If naive users are going to use the interpreter as a calculator, they're going to start off using floats and ints simply because they require less typing. My idea is to allow a gentle learning curve with Decimal (and Fraction) without scaring them off with exceptions or excessive warnings: a single warning per session would be okay, a warning after every operation would be excessive in my opinion, and exceptions by default would be right out.
That strikes me as a passive-aggressive way of saying we tolerate it for interactive use, but don't you dare mix them for real programs. A warning should be regarded as a bug in real programs — unless it's a transitional measure — so it might as well be an exception. Don't guess and all that. -- Adam Olsen, aka Rhamphoryncus
