Recursive Functions of Symbolic Expressions and Their Application
... A functional program is an expression, and executing a program means evaluating the expression. There is no state, meaning there are no variables. No assignments, since there is nothing to assign to. No sequencing. No repetition but recursive functions instead. Functions can be used more flexibly. ...

Testing an Optimising Compiler by Generating Random Lambda

As compilers often employ multi-stage processing before producing compiled code, in order to test later stages, earlier ones must be completed without error. The requirem ...
