Is there a general way to express pointwise operations over functions? in the simple cases we can use Through:
Through[(Sin+Cos)[1]]=Sin[1]+Cos[1]
However, if our function is more complicated, for example, Sin+Cos Exp then
Through[(Sin+Cos Exp)[1]]=Sin[1]+Cos Exp[1]
and we would like to obtain Sin[1]+Cos[1]Exp[1]. Is there some function F[expression,point] which returns the value of the expression in the point where the operations over functions are pointwise?
