[Python-Dev] Add more SyntaxWarnings?

[Chris Barker - NOAA Federal]

>. There's nothing mysterious about e.g. `TypeError: unsupported operand
type(s) for +: 'int' and 'str'`, unlike the case of the two concatenated
tuples. (Surely people get errors about int+str all the time, and they've
never complained -- unlike the tuple tuple case.)

Well, yes, that particular example is pretty clear. But as a rule, there
are a LOT of errors that can be pretty mysterious to newbies.

I would love to see Python become generally more informative with errors.

In this case, you’d probably get a similar error, but it’s still nice to
get it sooner, and if the hooks are in place, We could have others that are
really helpful.

Is there value in distinguishing

I don’t think so — what we need are helpful error messages. If it will be
raised at compile time, then it won’t generally be catchable in s
try-except— so the actual exception type isn’t very important.
