Macro
expr is a template expression (see template), clauses are test/expr pairs like cond. Evalautes the template on each test value, one at a time. If a test returns logical true, condt evaluates the corresponding expr and returns its value. If none of the tests are true, and there are an odd number of clauses, the last clause is evaluated, otherwise returns nil.
