- Alternative patterns can be given for a case clause using the - | operator. If any of the patterns match then the clause matches. -

-

- When matching on multiple subjects there must be the same number of patterns - as there are subjects. Try removing one of the _, sub-patterns to - see the compile time error that is returned. -

-

- If a pattern defines a variable then all of the alternative patterns for that - clause must also define a variable with the same name and same type. -

-

- Currently it is not possible to have nested alternative patterns, so the - pattern [1 | 2 | 3] is not valid. -
