I guess Maxima can't do it.

```
sage: inverse_laplace?
def inverse_laplace(ex, t, s):
r"""
Attempts to compute the inverse Laplace transform of
``self`` with respect to the variable `t` and
transform parameter `s`. If this function cannot find a
solution, a formal function is returned.
(%i1) display2d:false;
(%o1) false
(%i2) f(s):=%e^(-3*s)/(s+2);
(%o2) f(s):=%e^-(3*s)/(2+s)
(%i4) ilt(f(s),t,s);
(%o4) 'ilt(%e^-(3*s)/(s+2),t,s)
```

Does that answer things? If you want to file an enhancement request to Maxima, please do, maybe it's not so hard for them to implement; however, presumably there are arbitrarily hard ones like this that no system could do...
