The behaviour of match() when there is not exactly one thing matching seems a bit weird in general:

object buf = Stdio.Buffer("#4,7"); buf->match("#%d,%d");

That IS a bit weird, although not undocumented - if it matches multiple strings, it returns their concatenation. But since it's defined as returning the *sum*, this quirk happens. It's designed for a single match pattern and for that it generally does fine.

Definitely an amusing consequence though!
