示例1: consume_multiline_comment
void consume_multiline_comment(TokenizeContext& context)
{
int lookahead = 0;
// Keep track of the current depth, for nested blocks.
int depth = 0;
while (context.withinRange(lookahead)) {
if (context.next(lookahead) == '{' && context.next(lookahead + 1) == '-') {
// Found a comment opener, increase depth. Also advance lookahead so that
// we don't get confused by this: {-}
lookahead += 2;
depth++;
continue;
}
if (context.next(lookahead) == '-' && context.next(lookahead + 1) == '}') {
// Found a comment ender.
depth--;
