kill(all);

      Assigning a lambda function a name

f:lambda([x],x^2);

      Invoking the thusly named function

f(2);

      Mapping the function to
      a List of input values
      to produce
      a List of output values

map(f,[2,4,6]);

      Doing the same thing anonymously

map(lambda([x],x^2),[2,4,6]);

      Invoking a function with multiple arguments

apply(lambda([x,y],x*y),[2,3]);
