True, though that wasn't the workaround I was trying to remember.

Reading that, it doesn't seem like a final solution, so I'll post mine
anyway, in case it might be useful at some point.
Absolutely. Hmm, that is actually very useful to know. I wonder why
there is that huge difference? Note the Maxima warning...
{{{
solve: using arc-trig functions to get a solution.
Some solutions will be lost.
}}}
Yeah, I'll say! This is still right, as we expect.
{{{
(%i16) %solve(x7,phi);
(%o16) %union([phi = 2*%pi*%z21+%pi/2])
}}}
''This'' is something I can report to the Maxima bug tracker, and I'll do
so now.
