About it, I think it's too complex. Using integer id is faster than using 
string id, and the alias is a perfect mix of both.
I suggest the following:

- Just one type of AVP id as a string:
  $avp(name1) ...  $avp(name2)

- During the script parsing/compilation, each AVP name is converted to an 
integer, so the above AVP's would become:
  $avp(1) ... $avp(2)

- In this way, there is no need of alias id or integer id, the script would be 
as fast as now when using integer id and as readable as now using string id, 
making all of it simpler.

Which is exactly the advantage of *non* enabling that parameter? performance? 
low resources? since the AVP already exists in the transaction memory I can't 
imagine the benefict of making it not available during the transaction 
replies process.
