io-error and raise/strerror should include &error

[Derick Eddington]

... so they always raise &serious conditions, so if the base exception handler gets the condition, it does not return. (I'd say make the &error the first condition.) (I didn't look for any other spots that should but aren't raising a &serious.)

[leppie (leppie)]

&i/o inherits from &error so it is already an &error, similar, &error is already &serious.

[Derick Eddington (derick-eddington)]

Right, but io-error and raise/strerror don't always include an &i/o.

[Abdulaziz Ghuloum (aghuloum)]

Fixed in 1501. &error is now included by default unless the operation specifies otherwise. Leppie: yes, the &i/o conditions are &error, but adding an &error condition does not hurt.
