So we should break the contract (which most likely was just what the
implementation did at the time rather than a conscious decision, but I
wasn't there that many years ago), and break BC?

Ant allows to define property names with characters it uses to dereference
properties (a mistake I think), so how do you distinguish between the two?

I take it m4 doesn't allow to define a property/variable with $ and { and }
in its name, no? --DD
