I like this actually much more than the Ant way. Too
many times I created funny directories like ${src.dir}
et cetera. So I'm not going to miss this Ant "feature".
It would anyhow only apply for those using EL, for all
others, the old rule would apply (I assume here that
you could define on a higher level to use EL or not ..).
It may be difficult to have an EL in ant as the components/beans
(properties and references) are not bound by any naming
rules - so spaces, dots even < and > are allowed:
<property name="<x>" value="x is this"/>
properties and references have different rules (properties
are not meant to be overwritten) and have different
namespaces (i.e. one can use the same name for a property
and for a reference).
Traditionally in ant one uses nested elements in place of an EL.
<condition property="trax.impl.present">
<or>
<and>
<isset property="javax.xml.transform.TransformerFactory"/>
<available classname="${javax.xml.transform.TransformerFactory}"
classpathref="classpath"/>
</and>
<available
resource="META-INF/services/javax.xml.transform.TransformerFactory"/>
</or>
</condition>
{from ant's build file}
but this can get a bit verbose.

Deadly serious for me ;-) as well as I hope that Peter
has not been joking with regards to "- add logic/control-
flow features from jsp/ant-contrib (for, if, while, try,
var etc)

Kidding?

1. I'm not sure how serious it was
2. its a traumatic change
3. I dont actually like EL handling as the way any invalid bit the the
expression switches the whole thing to null, instead of telling where
you've left something undefined. That may just be the JSP2
implementation, of course,.
