Nathan Bubna commented on VELOCITY-630:
---------------------------------------
In this the "Strange pass by name behavior" thread on the dev list, Byron
points out that the changes made for VELOCITY-285 don't fit with strict
pass-by-name behavior. I'm convinced at this point. In the absence of any
argument against that. I'm going to revert the relevant change in VELOCITY-285
in favor of resolving this issue. Here's the thread for anyone interested:

> Pass by name does not work with #foreach within a macro

> Key: VELOCITY-630
> URL: https://issues.apache.org/jira/browse/VELOCITY-630
> Project: Velocity
> Issue Type: Bug
> Components: Engine
> Affects Versions: 1.5, 1.6-beta1
> Reporter: Byron Foster
> Attachments: Velocity630TestCase.java
>
>
> GIven the following:
> #macro(test $a $b)
> #foreach($i in $a) $b #end
> #end
> #test( [1, 2, 3] "#if($i == 2) yes #else no #end")
> I would expect the output:
> no yes no
> Instead, I get
> no no no
> The Foreach directive explicitly sets $i in the localscope. This change was
> made for VELOCITY-285 . Before 285 Velocity correctly gave the results "no
> yes no" which is svn revision number 471881.
