Comment (by mabshoff):
The issue is the following:
{{{
[10:34am] wstein|afk: mabshoff -- all that #random does is the following.
[10:35am] wstein|afk: sage: foo # random
[10:35am] wstein|afk: gets replaced by
[10:35am] wstein|afk: sage: _ = foo
[10:35am] wstein|afk: That's it.
[10:35am] mabshoff: mhh
[10:35am] wstein|afk: So it won't work at all with exceptions.
[10:35am] wstein|afk: Better might be:
[10:35am] wstein|afk: sage: foo # random
[10:35am] wstein|afk: gets replaced by
[10:35am] wstein|afk: sage: foo
[10:35am] wstein|afk: ...
[10:35am] wstein|afk: If that worked.
[10:35am] wstein|afk: I didn't know about ... when I wrote # random.
}}}
The goal now is to get 3.2 out and the easiest way to do this is to nuke
the affected doctests and then deal with {{{#random}}} properly in 3.2.1.
Cheers,
Michael
