-Nesting the switch inside of the catch clause is awkward and introduces additional nesting. It also defeats the purpose of supporting pattern matching in catch clauses. Splitting the code up into multiple catch clauses requires duplication, which is also undesirable. Supporting a multi-pattern catch clause would allow for code which is both clearer and more concise.

 ## Proposed solution
 
-Catch clauses should allow the user to specify a comma-separated list of patterns. If an error thrown at runtime in a do block matches any of the patterns in a corresponding catch clause, that catch clause should be executed. Similar to switch cases, a user should be able to bind a variable in all patterns of a catch clause and then use it in the body.

 Additionally, conditional compilation directives should be permitted to appear surrounding catch clauses.
