-1 no labels. keep VTL simple, please. it's not java, nor should it be. the ease of teaching it and reading it are important to me. FYI, i'm also still considering vetoing the #foreach( $user in $users index $i ) syntax, since i think it is ugly, unclear, and unnecessary. the more i look at it, the more i dislike it. having that syntax in combo with this one would make my eyes water. (please bear with my grumpy bluntness; i like you, i'm just very concerned about syntax choices.)
if you really feel it is necessary to control the break level, there is always the LoopTool in velocity tools. yes, that's not that pretty either, but that is part of the point of VelocityTools. keep ugly, but sometimes desirable features out of the core.
if you really feel it is important to have some better break control in the core, let's discuss other ways. like perhaps an optional integer argument for #break, to indicate how many levels to break out of. Something like that would at least avoid "uglifying" the #foreach syntax, for an unnecessary feature.
