It depends...
Sometimes i will shuffle things under a method (static one if there are no
captures and use a method ref).
If i get *really* fed up i have been know to write stuff like the following:
private static interface S<T, E extends IOException> {
T apply() throws E;
}
private static <T, E extends IOException> T r(S<T, E> s) {
try {
return s.apply();
}
catch (IOException t) {
throw new UncheckedIOException(t);
}
}
