It's already allowed by the example; there are about 1800 instances in the
tree; and disallowing it would lead to
if (a) {
...
} else {
if (b) {
...
} else {
if (c) {
...
} else {
if (d) {
...
} else {
...
}
}
}
}
instead of
if (a) {
...
} else if (b) {
...
} else if (c) {
...
} else if (d) {
...
} else {
...
}
which is more readable.

An exception is the opening brace for a function; for reasons of tradition
and clarity it comes on a line by itself:
