Assignments are equivalent to gotos. Just write the function as a big
loop case .. statement, then you can use assignments as goto.
In functional programming languages like ML or Scheme it is possible
and easy to write assignless code, but these have lots of special tools
(e.g. easy closures) that make that easier.
