Probably. But is performance relevant to the use cases we intend them
to be used? I'm not sure; I've got the impression that the use cases
Phillip had in mind are all in the context of debugging. After all,
why else would you want to write something to a standard stream in an
_interactive_ session? And how is performance relevant to debugging
printfs?

I'm not so sure. But that's not the important part of my reasoning.
