If you don't like indentation you can simply ignore it or you
can use old goto :)

outer:
BTW there is a trick to avoid goto+label:
switch (true) {
default:
int i = someFunc();
if (i < 0) break;
...
}
If code after goto is long, the reader has to search for the
label. With switch/break, the reader knows the current scope is
just skipped, no need to interrupt reading of lines.
We could allow omitting the condition and default label:
switch {
int i = someFunc();
if (i < 0) break;
...
}
That would encourage the pattern to be used instead of the
'triangle if' pattern - the rationale for breakable blocks:
