24726,Sage silently accepts symbolic expressions with two comparison operators,tmonteil,,"See the following example:
{{{
sage: 0 <= x <= 1/2
0 <= x
}}}
This should raise an error. Note that it can create confusion when used in assumptions:
{{{
sage: assume(0 <= x <= 1/2)
sage: bool(x <= 1/2)
False
}}}
