Comment (by vdelecroix):
other remark: If I understand correctly `satisfiable` would corresponds to
a '''exists''' quantifier for '''all''' the variables in the formula.
While the `holds` would correspond to '''for all'''. What about something
more elaborate such as
{{{
for all x, exists y, for all z expr(x,y,z)
}}}
