Oops, indeed I mistook the function handles returned by inline as functions.

Well, functions defined in the command line either by inline or function
keyword would find undefined variables from the top-level environment (if
they exist) and store their value. Something like:

> a = 1;
> f = inline("x + a", "x");
> f(1)
ans = 2
> a = pi;
> f(1)
ans = 2

Looks straightforward, but there might be all kinds of subtleties I'm not
aware of...
