integrating over a symfun

hello,
can I integrate over a symfun ?
the following doesn't work:
---
syms f(x)
f(x)=x+2 %just a simple example
ans=integral(f,1,2) % for integrating over f(x) between x=[1,2]
---
any ideas ? thanks !

Using matlabFunction(f) works:
syms f(x)
f(x) = x+2
ans = integral(matlabFunction(f),1,2)
