a:=1;
b:=a*x+1;
as_function_of(b,a)

Very useful for defining functions within a program

It will not work inside a program, it's designed for locus in the Xcas geometry screen, it is using an internal history mechanism. If you want to build a function from an expression, the right function is unapply.
