I think it reads well with "as" also. +1
To me it's a filter statement. So would catching multiple exceptions
have the form:
except (<type>, <type>) as <name>:
The value is bound to the name if it's type is in the sequence. This
would be an indirect assignment similar to.
if value in list: name = value
Which you can't do directly because you don't have access to the value
yet. That's not too different than import which is also an indirect
name binding operation of a value you don't have yet.
