----------------------------------

    Affects Version/s:     (was: 1.7)
                       2.0

> Macro pass by value option
> --------------------------
> 
> Key: VELOCITY-687
> URL: https://issues.apache.org/jira/browse/VELOCITY-687
> Project: Velocity
> Issue Type: New Feature
> Components: Engine
> Affects Versions: 2.0
> Reporter: Byron Foster
> Attachments: value.patch
> 
> 
> Add a configuration property which would change macro parameter passing from pass \
> by name, to pass by value.  I think in many instances this option will provide \
> behavior that is more intuitive to the user.  There are two important exceptions to \
> this, references created by #define, and references created by BlockMacro's \
> $bodyContent.   This allows the user to still specify pass by name semantics when \
> desired, for example: #define($x) #if($foo)$foo.bar#{else}-None-#end  #end
> #go($x)
> In the above example '#if($foo)$foo.bar#{else}-None-#end' will be passed by name.  \
> In all other cases pass by value rules apply for example: #go($foo.bar  [1, 2, 3]  \
> #if($bar)Yes#{else}No#end) In the above example all parameters will be evaluated to \
> a value first, then passed to #go.  This has potential performance improvements \
> also.
