So how should lua be made available to yum?

Current implementation of lua in rpm is through %{lua: ...} macro 
constructs,
grotesque mainly because of the necessity to preserver a "stable" and 
constant
rpm-python interface. E.g. there is no way to simply expand a macro, one 
has to
go through the baggage of hdr.sprintf() where rpmExpand() to invoke lua 
happens
as side effect. That's obscure enough to pass for "stable", sigh.

Easy enough to rip several layers off the above, what stops is no need 
to do so yet.

Hum a few notes about what you'ld like to see lua used for in yum, 
please. I think
lua has definite and positive benefits for rpm packaging, becuase for 
the first time
rpmlib can run scripts without the baggage of scriptlet dependencies. 
Lots of dependencies
would (will imho)  simply melt away if lua rather than shell were used 
for the 20 or so
common operations performed by package scriptlets.
