C-style for statements are very easy to parse, if the language is at
all C-like, and very powerful. Although they /can/ be cryptic, they
are also more versatile than simple indexed for statments. Also, for
a C or C++ programmer - or a Java one even - having a C-style for
statement seems logical.


A C-style for statement can be expressed as a while statement trivially:


      for (init_expr; test_expr; increment_expr)
          statements;


equates to:


      init_expr;
      while (test_expr)
      {
          statements;
          increment_expr;
      }


The only even slightly tricky part is that the test expression defaults
to true. So:


      for (;;)
          statements;


equates to:


      while (true)
          statements;


Cryptic maybe, depending on the way the programmer uses it, but not
exactly difficult.
