Which is fine if you're the only person who will look at this code and we're talking about a timespan of a few hours.

When someone comes to deal with this code a year later, it makes life more difficult than it needs to be; at least the C# way is explicit - you can come back to that years later and know exactly what's happening.

(Which is the basic problem with most of Perl's magic - coming back to it hours/months/years later makes life harder for no actual gain.)
