Just for posterity, I use this inside a little method for wrapping lambdify:
deprimer={n:symbols(n.name.replace("'","lambdify_prime")) for n in
eq.free_symbols if "'" in n.name}
eq=eq.subs(deprimer)
where "eq" is the equation to be lambdified. I also need to deprime other
references to the symbols in the call, and make the equation not an
equation, but this is the gist of it.
