I have no idea whether this is possible or not, but one area where I
think Python needs help is the detail of the exceptions. For example,
would it be possible at all to have at least the two uncoercable types
listed ("first argument is a single precision float, second argument is
a double precision float")?
PS: This doesn't have to be in the next release, just something to keep
in mind. A certain set of users at least will want to use the array
tool in an interactive context, where these things matter a lot.
