While this works as expected:
{{{
sage: n = var('n')
sage: assume(n, 'integer')
sage: solve([n^2 == 3],n)
[]
}}}
this does not:
{{{
sage: forget()
sage: n = var('n', domain='integer')
sage: solve([n^2 == 3],n)
[n == -sqrt(3), n == sqrt(3)]
}}}
So, either `solve` should also look at the variable domain, or better,
let's propagate domain settings to the assumption list.
