Hi!
The most straight forward way does not work:
sage: def bla(x):
: print "here I am"
: return x**2

sage: foo = function("foo", nargs=1, eval_func = bla)
sage: foo(5)
---
TypeError

Certainly it is a good idea.
Concerning feasibility: I am not

And, as we know now, if we do this in the notebook, we can even change
the value of 2 afterwards:
def f(x):
return 2*x
print f(3)
_sage_const_2=3
print f

It's better to define

b(x) = 2*x
