What are some thoughts on making this #global instead of #local such that
global vars are set instead of locals? I think it is far more likely that a
developer intends assignments in a macro to be local by default then global.
you don't have to look far into the language world to see this is the trend.
#global is needed for the 'velocimacro.context.localscope=true' property
(Which I think should be the default anyway)

> Key: VELOCITY-680
> URL: https://issues.apache.org/jira/browse/VELOCITY-680
> Project: Velocity
> Issue Type: New Feature
> Affects Versions: 1.7
> Reporter: Jarkko Viinamäki
> Attachments: velocity-local-directive.patch

>
> It would be very useful to be able to set variables that are in local macro
> scope. That is, they do not overwrite "global" variables and are thrown away
> after macro rendering. This would allow people to build macro libraries that
> do not clash so easily with each other.
> There is some implementation of a "LocalDirective" in
> experimental/localdirective but I didn't quite get it and it doesn't follow
> the same syntax as #set. I used a few minutes to hack together this
> alternative implementation which behaves exactly like #set but it puts things
> in local context only.
> There's only one test case since this is Request-for-Comments type of patch.
