As written, that suggestion scares me slightly, because its behaviour
wouldn't be entirely obvious that it does that.
I'd be fine with a system like:
my $error_state = save_errors();
...
restore_errors($error_state);
return $value;
Or
return preserve_errors(sub{
/* code that can generate errors that shouldn't leak */
});
Just lumping it in with the "Context" object seems too magical.
