bq. That's why I was asking for a specific use case
What I can tell you is that we did fixed several codes in XWiki Standard doing
that but I agree with you that it was mistakes in both cases. So yes I don't
have a strong use case to describe but any weird behavior always end up being
expected and used in 10 years :) From what I understand the reason for this
behavior in 1.7 is a side effect of the local macro context which does not
exist anymore and I guess it not really easy to get back this behavior without
getting back the local macro context which you said you did not wanted anymore
even as a retro compatible option.

> 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.
