Description (last modified by )
Both sin and cos are functions of one (undetermined) variable, and can be called, but when one performs arithmetic on them this changes.
Maybe there should be a CallableSymbolicExpressionRing? with an unnamed variable that coerces into any CallableSymbolicExpressionRing? with a specified variable name?
sage: f = sin sage: g = cos sage: f(1) sin(1) sage: g(1) cos(1) sage: h = f+g sage: h(1) sin + cos # should be sin(1)+cos(1) sage: f = 3*sin sage: f(1) 3*sin # should be 3*sin(1)

Also should have
sage: f(x) = x^2 sage: f + sin x |--> sin(x) + x^2
