bq. Could you give me an example where the former behavior would be important
for backward compatibility?
Any change is important for backward compatibility. As usual I'm not discussing
how valid this behavior is but the fact that this behavior is expected and will
break things.

> Key: VELOCITY-926
> URL: https://issues.apache.org/jira/browse/VELOCITY-926
> Project: Velocity
> Issue Type: Bug
> Components: Engine
> Affects Versions: 2.0, 2.1
> Reporter: Claude Brisson
> Assignee: Claude Brisson
> Priority: Major
> Fix For: 2.2
>
>
> Consider the following example:
> {code}
> #macro( test $foo $bar )
> $foo $bar
> #end
> #set($foo = 'foo')
> #set($bar = 'bar')
> #test( $bar, $foo )
> {code}
> The expected result would be "{{bar foo}}", but since 2.0 we get the
> incorrect result "{{bar bar}}", as if the first inner {{$foo}} macro argument
> was overwritting the second argument evaluation.
