Agree. Note that the similar operator (`try!(...)`) in Rust does not *suppress* errors, but rather just simplifies handling of the error (in Rust, expressed using a Result object); if an error is returned it immediately returns from the outer function with the Result object; otherwise it evaluates to the (unwrapped from the Result object) success value. This is closer to the try expression you bring up, just with some slightly more opinionated handling. ~TJ _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
