 Write a program that reads a line of input from the user, and responds by repeating the input back to the user.

+You may want to implement this by storing the user's input into a variable, and then passing that variable into your language's `print` function.

+This program should work in a loop; in other words, once the string has been printed, the program should return to its initial state, asking the user for their input once again.

+If you're using a functional-style language, you may want to use an algebraic data type to do this; if you're in an OOP-style language, you may want to use classes instead.

+Next, you should write the lexer, which converts an input string into a list of tokens.

+Your language of choice likely has built in functions to convert a string to an integer (Python has `int`, Haskell has `read`, Rust has `string.parse::<i32>()`). You'll probably want to use one of these functions to determine if a literal is a symbol or an integer.

 Next, define a function called `eval`, which takes an AST as its only parameter, and reduces any redexes, returning the resultant value.
 
 Update your REPL function, by running `eval` on the parsed input, and passing the resulting value into `print`. You now have a fancy calculator!
