When I try same expression in the emulator, above return only 24, without warning.
I beiieve (x^3)''(x = 4) equivalent to subst((x^3)'', x = 4), only less typing.

That's interesting. That's exactly what I was hoping to accomplish.
What version are you using? I tried this on the following versions:

2020-01-16 (HW-A, VC)
no warning, returns 24

2020-09-08 (HW-A), 2021-05-05 (HW-D), 2021-06-09 (VC)
has warning, returns 6*x=24
