Okay, thanks for that info. That's good to know.

Code:

diff(x^3,x,2)(x = 4)

That's an interesting notation. It appears to work for other functions as well. Is there any way to use it with primes? When I try (x^3)''(x = 4) it gives a warning and returns (6*x) = 24, with the expression on the left and the result on the right. Is this the intended behavior?

For that expression, the pipe does work

(x^3) | (x = 4) 64
