[Logs-devel] LoGS variables

[Jim Prewett]

Hi All,

I've been thinking about how variables work within LoGS.  Vijay and I have 
had a couple of offline conversations about this.

I think that the way that variables work right now is broken and needs to 
be addressed, re-thought, re-worked, etc.

Right now, for a variable to be set in a match function, it must be 
returned as a list of lists of variable and value like: 
((FOO 42)(BAR "something")) to set FOO to 42 and BAR to "something".  
These variables are then bound with a progv (creating a dynamic variable 
binding, which, I believe is the problem) before the action function is 
run.

How else could we, essentially, maintain a stack of these variables (so 
that a ruleset could bind a variable, and a rule within that ruleset bind 
the variable to a different value) ? 

Any ideas?

Jim
