This is not *quite* true. If you use "$!{name}", ant will strip the "$", so 
you'll see "!{name}" as the value. (This is because ant strips all single "$" 
characters without warning, unless they are part of a "${...}" construct.) 
You'll need to use "$$!{name}" instead.

(One slightly bizarre result of the current behaviour is that "$${propX}" and 
"${propX}" produce identical output when propX is undefined.)
