This allows for errors to be "re-thrown" by yielding any error as the
result of a catch block. For example:
```zig
fn errorable() !void {
return error.FallingOutOfPlane;
}
fn foo(have_parachute: bool) !void {
return errorable() catch |err| b: {
if (have_parachute) {
// error trace will include the call to errorable()
break :b error.NoParachute;
} else {
return;
}
};
}
pub fn main() !void {
// Anything that returns a non-error does not pollute the error trace.
try foo(true);
// This error trace will still include errorable(), whose error was "re-thrown" by foo()
try foo(false);
}
```
