Nathan Bubna commented on VELOCITY-700:
---------------------------------------
-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.

> if the last argument to to the #foreach directive is a word, then that word
> serves as a label to indicate the break level for the #break directive. Par
> exemple:
> #foreach($user in $users outer)
> #foreach($email in $user.emails)
> #if($email.expired)
> #break(outer)
> #end
> #end
> #end
