Just a stylistic suggestion: I now rather dislike the if-else form, and
prefer pattern-matching like forms.

Consequently, I tend to now use ternary operators in my C and C# code
which results in such a clearer form. The above function would look
something like:

def fact x =
  (x == 0) ? 1:
  (x < 0)  ? - fact(-x):
             x * fact(x - 1);

I'm not suggesting ternary operators or pattern matching here, just
supporting the idea of a syntax for conditionals where nested/chained
conditionals have a more readable structure.
