The syntax was inspired by OCamls pattern matching syntax:

match object with
  pattern1    ->  result1
| pattern2    ->  result2
| pattern3    ->  result3
    ...

But for Python we have to look for an expression not a statement
syntax. In order to prevent ambiguities I used a double bar '||'
instead of a single one.
