bs.open does not convert from ReasonML
exception Error(string);
let handlePromiseFailure =
[@bs.open]
(
fun
| Error(_) => ()
);
Formats into
exception Error(string)
let handlePromiseFailure = x =>
switch x {
| Error(_) => ()
}
The whole @bs.open
is gone. I also have no idea how to express the code in the new rescript syntax.

I think this is not a legacy way of handling exceptions as it has been introduced in 0.7 (https://github.com/rescript-lang/rescript-compiler/blob/master/site/docsource/Exception-handling.adoc#bsopen-type-safe-external-data-source-handling-since-170).
Sorry about this, we don't yet supported this in the new syntax.
You can leave it in the old syntax or write the code that bs.open
expands to:

I'm currently focused on infix operators and some printer improvements, will look into this after those.
Thanks!
This syntax feature might be irrelevant in the future (aka proper new promise api)
