Ian,
Be sure to check my test1 release of EE. I've implemented the syntax
suggested by Martin and I cannot live without it any more. It's ultra-clean,
doesn't break builds (hopefully) and works for all attributes regardless of
their type.
One more argument for allowing properties in expressions to be written
without "$": Compare:
<echo message="aaa" if="${endswith(${somefilename},${extension})}" />
with
<echo message="aaa" if="${endswith(somefilename,extension)}" />
The ugliness factor is close to zero in the latter case, IMHO.
Jarek
