Public bug reported:

When calling f(...) on a Function f, the input arguments seem poorly
checked. This is error-prone. It would be good to check that the
coordinates input match the geometrical dimension of the mesh

Example:

from dolfin import *

mesh = UnitSquare(4, 4)
V = FunctionSpace(mesh, "CG", 1)
f = Function(V)
for i in range(len(f.vector())):
    f.vector()[i] = i + 1

print f(1.0)
print f(1.0, 1.0)
print f(1.0, 1.0, 1.0)
print f(1.0, 1.0, 1.0, 1.0)
print
print f((1.0,))
print f((1.0, 1.0))
print f((1.0, 1.0, 1.0))
