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
