How the new version achieves this: `diff(x(t)y(t))` in the latest version? `sage: t = var(’t’) sage: x = function(’x’, t) sage: y = function(’y’, t) sage: diff(x(t)*y(t),t) TypeError: Substitution using function-call syntax and unnamed arguments has been removed. You can use named arguments instead, like EXPR(x=..., y=...)`
