XO0175: two statements or arms on one line

Newlines terminate statements and separate declarations and match arms, and Xo has no semicolons in source (core 1.3). Two statements, declarations, or arms on one line are rejected. Put each on its own line. Several match or select arms on one line (match r { Ok(v) => v Err(_) => 0 }) get a machine fix that puts each arm on its own line (xo fix), and the parser keeps every arm, so no false missing arm error (XO0301) follows.

Example

fn a() {}
fn b() {}

fn f() {
  a() b()
}

Fix

fn a() {}
fn b() {}

fn f() {
  a()
  b()
}
