Yes. PropertyHelper is a property interceptor, and it simply rocks.
In essence, you register a helper with Ant. Then, at each request for a property, each registered helper is asked for the property value in turn; the first one that has it, returns it.
Completely not following this property helper discussion up to this point so I may be repeating something, (forgive me if I am) but this sounds like the results of the request for a property could change if a new property helper gets added... Does this break immutability? It may be that the value of a property object never changes, but if the value of ${foo} is one thing and then becomes another when a helper is added.... I suspect whatever you have done is not going to cause this, but what about someone writing a custom task that intentionally adds and removes property helpers. What happens if someone writes a <setproperty> task built on this idea? what happens if the property helper intercepts built in things like ${basedir}? Sounds like the basis for a possible <chdir> task :). Sounds highly abusable to me...
If you have set it up so ant doesn't accept new property helpers after it starts executing the file, then this probably isn't an issue...
Just curious, -Gus
