But this is no more or less shadowing than me making one of the 
<ant> calls passing a <param> with the value of the local. The
effect is exactly the same. And as any changes made by the <ant>
execution will have no effect on the caller, I see no issue.

I think it is a mistake that <local> if local is not visible across
<ant>, if that were the case then it should not be visible across
<macrodef> either. If it is visible in one case, so it should in the

Otherwise you get this extremely wird behavior:

 <macrodef name="m">
    <equals arg1="${p}" arg2="my local p"/>
  	<antcall target="tm"/>

 <target name="x">
   <local name="p" value="my local p">

 <target name="tm">

 <property name="p" value="my global p"/>

 [echo] my local p
 [echo] my global p

How on earth by looking at "m" can you even realize what will
happen in the <antcall>? You may have done many checks to properties
to decide whether the antcall should be made or not, and then once you
do the call, it turns out the <antcall> receives completely different
properties than the one you tested. I do not know how such behavior can 
make sense to anyone.
