You might be able to wrap your expression so as to create a function
instead, and call the function with the values of the variables that the
actual expression depends on. In Python, because I haven't learned to
construct expressions in Julia yet and don't have the time to learn it now:
def f(x): return eval("lambda x: x + 1")(x)
