Use a scoped block for inlined return statements.

Inlined return statements emit two statements--an assignment, then a
break. If scope braces are otherwise missing, the break statement will
end up in the wrong place. i.e.:

Mistranslated:
	if (foo) return bar;  --> if (foo) out = bar; break;

Translated properly:
	if (foo) return bar;  --> if (foo) { out = bar; break; }
