----------------------------+----------------------------
Only the modern syntax of the except clause (in the try-except statement)
is accepted by Python 3. [[br]]
Changes according to {{{lib2to3/fixes/fix_except.py}}}:
{{{
- "except E, T:" where T is a name:
except E as T:
- "except E, T:" where T is not a name, tuple or list:
except E as t:
T = t
This is done because the target of an "except" clause must be a
name.
- "except E, T:" where T is a tuple or list literal:
except E as t:
T = t.args
}}}
