I'd also be in trouble if someone else named a contract or function
with my credit card information.  But the contract is more likely --
function names tend to be static, but contracts can be named
dynamically; for instance, a >=/c inside an ->d will include its
argument in its name.  Not that a lot of Planet code is dealing with
credit card information these days, but personally I prefer an
application to ask me before sending data back, and let me see the
data to decide.  Saving it up and sending it off without asking is
just looking for trouble.

Planet code -- some of it anyway -- is licensed such that it can be
used in proprietary applications.  If we really mean for people to use
it this way, I'm not sure we have the right to start arbitrarily
downloading users' data.
