What about instead of at the end, we do it at the beginning?
try ignore (SomeIgnorableException, OtherException) {
// break stuff
} catch(UnexpectedException) {
// fix stuff
} finally {
// do this anyway
}
Since ignore only can follow a try and any symbol other than a "{" is currently
an error, I don't think we don't need to reserve "ignore" as a keyword.
It appears to be relatively easy to scan/read as well.
