Right. There's a rule, Dojo follows it IIRC, to prepend ; to all files, always. That will do the trick.
But of course people don't all folllow that rule and nothing enforces it.
Concatenation is never safe when done blindly, but "use strict" ups the ante. The particular problem is that browsers aren't yet checking "use strict", so erroneous content is getting out into the wild.
