Request: Symbol of Assigning Differental Equation #33

I am not sure if this notation is common in the world, but how about supporting the notation of assigning values to differentiated functions in physica?

below code shows above image with normal typst.

$
  lr((dif) / (dif t) L(x(t))|)_(t=0)
$

or with physica, 

$
  lr(dv(, t)L(x(t))|)_(t=0)
$

Since this needs lr and is difficult for the public to understand, how about giving some support with physica?

Maybe #28 would help?

Oh I had missed eval function. Thank you for telling.
