Yes, that would throw an exception, but that wasn't my example. I created a
value for $map first. I don't see the relevance.

Sorry, I misunderstood your comment before. You are saying that your tried it
with this patch applied. Yes, it doesn't work with strict mode now, but when
this patch is applied I'll add strict mode to it.
<qoute>
As for whether #local or #global is more useful, i see your point, but the fact
remains that velocimacro.context.localscope defaults to false, and i would bet
money that a significant majority of users leave it that way (myself included).
</qoute>
Sure, with the current situation of not having any global scope control the
current default setting is the one of more utility for the reasons above. In
my personal use I also run Velocity in the default mode precisely for this
reason. But as soon as there is a #global directive I will change.
Anyway, that's why we have properties so people can bend Velocity to there will
:) I'm +1 for this patch, and +1 for the name #local.

> 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.
