Notice that following this path (not making locals visible) means
that <macrodef> defined tasks will behave differently than java written
tasks, more over it means that macrodef is not really the same as having
the code in place. Ex:
<macrodef name="m">
<echo>${a}</echo>
</macrodef>
<property name="a" value="G"/>
<target name="x">
<local name="a" value="L"/>
<echo>${a}</echo>
</target>
<target name="y">
<local name="a" value="L"/>
<m/>
</target>
Targets x and y are suppose to do the same thing, at least
that is what a "macro" is supposed to do. But here the behavior
changes in unexpected ways depending on whether "a" is local or global.
If I had written <m/> in java, I would see the local value, but since
I wrote it using <macrodef/> that is not the same. So I can forget
about writing new tasks by just composing existing tasks toguether. :-(
