Here's the re-write; it wasn't quite as simple as I implied, but it's still trivial: "What they thought was best" is not, in general, the same as "What they pleased". For instance, some implementers might have been pleased to insert warning messages that made fun of people whose politics they disagreed with. But what they thought was best probably didn't include losing that portion of their potential market which would have been offended by such messages, nor that additional share of their potential market that might have felt that such warning messages showed insufficient professionalism. I tried to come up with an example that more directly applies the evaluation order of operands, but I had a hard time coming up with any plausible examples where an implementor might have been pleased to do something other than what they thought best. > That said, the point you made is quite valid.

I don't think that element is a big one. Implementors who pay attention to the needs of their customers tend to find their choices significantly constrained by those needs, and so long as they work within those constraints, they tend to have more customers than those implementers who let caprice and arbitrariness rule their designs.
