Hello all,
In order to help make things regarding this casting issue more
explicit, let me present the following table of potential "down-casts".
(Also, for the record, nobody is proposing automatic up-casting of
any kind. The proposals on the table focus on preventing some or all
implicit

Another possible approach is to treat downcasting similar to underflow. That
is give it it's own flag in the errstate and people can set it to ignore,
warn or raise on downcasting as desired. One could potentially have two
flags, one for downcasting across kinds (float->int, int->bool) and one for

Hi All,
I'm thinking that one way to make the automatic type conversion a bit safer
to use would be to add a CASTABLE flag to arrays. Then we could write
something like
a[...] = typecast(b)
where typecast returns a view of b with the CASTABLE flag set so that the
assignment operator can check wh
