[Caml-list] Syntax for several matches, each with a "when" clause, but only one result

Dear OCaml Users,

sometimes I want to do something like

match expr with
| case1 when cond1
| case2 when cond2
| case3 when cond3 -> result

but this doesn't work. I have to write

match expr with
| case1 when cond1 -> result
| case2 when cond2 -> result
| case3 when cond3 -> result

Usually only some of the matches have a when clause. Is there a way to avoid copying the result term (other than writing a function) ?

Best regards,

Michael
