Christopher Schultz commented on VELOCITY-773:
----------------------------------------------

What implications does this have for code like this:

#foreach($foo in $foos)
  #set($foreach.someVar = 'some value')
  #foreach($bar in $bars)
    .. terribly interesting stuff
  #end

  $foreach.someVar
#end

Does each foreach loop create a nested Context in which vars are defined and 
then cleared? Otherwise, the behavior of nested foreach loops might surprise 
some people.

> Provide locally scoped #set variables

> Consider this snippet:
> <!-- Generated pushbutton groups -->
> #foreach ($group in $form.pushbuttonGroups)
> <div class="die-button-group" style="#coordinates($group)">
> #*    *##foreach ($groupChild in $group.children)
> #*            *##if (!$velocityHasNext)#set($turnPaddingOff = 
> 'style="padding-bottom: 0px;"')#end
> #*            *##if ($groupChild.class.simpleName == "Pushbutton")
>       #*      *#<div $!turnPaddingOff>
>               #*      *#<button type="submit" name="$groupChild.name" 
> value="$groupChild.value" 
> onclick="loadSubsequent()">#label($groupChild.label)</button>
>                               
>       #*      *#</div>
> #*            *##end
> #*    *##end
> </div>
> #end
> There is an inherent bug. After the first run of the outer foreach, the var 
> turnPaddingOff is still available and will always set in the div tag. There 
> is only one workaround. At the end of the outer foreach you have to set it to 
> ''.
> #set should be available as a locally scoped thing in #foreach or other 
> constructs.
