Expression evaluation refers to the process of mathematically analyzing and computing the value of complex mathematical expressions in computer programs. It is particularly important in scientific computing and engineering applications, where large and intricate expressions are commonly used to solve computation...
Let’s say you have an expression which you want to evaluate multiple times but with different parameters. Currently the Evaluate method will parse and compile the expression tree for every evaluation even thought the expression is same every time. As the compilation of expression trees is an exp...

, its approach is quite similar to that of the old one, i.e., it will walk the AST, directly compute a value from that and return it. However, it does all the work in only one AST visitor (or, more accurately, two: one for bytecode generation and one for direct evaluation)....
