I just noticed

and the fact that Eric Evans already had this idea a year before me.
I apologise for not having done my research, at least we have two
implementations now (and we both use @VAR@ syntax).

Anyway there's one difference: Eric proposes to compile rules files,
I propose to parse rules at run-time. If I look at

then I am moderately sure that a user or even our humble selfs will
prefer to read the more abstract variable-using syntax instead.

I am really in favour of this and would start to implement run-time
translation as soon as I hear people who're also in favour.
