New issue 3638 by skirpic...@gmail.com: Automatic series expansion while applying a function?
http://code.google.com/p/sympy/issues/detail?id=3638

Mathematica does so
{{{
In[1]:= Tanh[Series[Sin[x], {x, 0, 5}]]
Out[1]=
     3       5
    x    37 x        6
x - -- + ----- + O[x]
    2     120
}}}

Does it make sense for SymPy?

If so, the trivial way to include this feature is to overload eval() inside of every Function's child class. But this code looks as very generic (see attached example) - should this be implemented in the Application's eval()?
