Comment #14 on issue 1612 by asmeurer: Symbol('f')(x) != Function('f')(x)

No, that too depends on caching:
Aaron-Meurer:sympy-scratch aaronmeurer(mathjax$%)$./bin/isympy
IPython console for SymPy 0.7.0-git (Python 2.7.2-64-bit) (ground types:
gmpy)
These commands were executed:
from __future__ import division
from sympy import *
x, y, z, t = symbols('x y z t')
k, m, n = symbols('k m n', integer=True)
f, g, h = symbols('f g h', cls=Function)

In [1]: Function('f', nargs=1)(x) == Symbol('f')(x)
Out[1]: True
