I don't think your proposal will be an enhancement. For two reasons.
1. x (x) an x*(x) have the same amount of characters.
2. currently the python and sage expressions are not white space dependant.
Your suggestion would introduce such a whitespace dependancy and will be
very unexpected for a l
Thanks - this is exactly what I meant by resolved.

I meant to say "If f is a symbolic expression...". If it is a properly
defined function in two variables x,y, then f(2,3) is fine.

The use of implicit multiplication is a very improper way to talk with
a CAS, IMHO. You met one of the reasons why it is improper and error
prone.
I want "x (x)" to return x^2. It doesn't seem to work with any
implicit_multiplication level. What does the following error mean?
Does it mean this will get fixed in a future version?
sage: x (x)
/usr/local/sage-4.7/local/lib/python2.6/site-packages/IPython/iplib.py:
2073: DeprecationWarning: S
sage: (integrate( exp(-x^2/2)/sqrt(2*pi) * sign(x-1), x, -oo, 1 )
+integrate( exp(-x^2/2)/sqrt(2*pi) * sign(x-1), x, 1,
oo )).simplify_full()
-erf(1/2*sqrt(2))
