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=...)

The following works in SageMathCell:

t = var('t')
x = function('x')(t) 
y = function('y')(t) 
diff(x*y,t)
