What do you mean?
I thought about something like this:
<something1: bla-bla>
xxx:yyy
zzz:qqq
<something2: bla2-bla2>
www:eee
rrr:ttt
</something2>
</something1>
And interface:
a=conf["something1=bla-bla:xxx"] //a=yyy
a=conf["something1=bla-bla|something2=bla2-bla2:www"] //a=eee

There's a problem: url needs a pretty specific comparation.
So that we need some new class
ConfigItem something1 with virtual methods.
And url,server derived from ConfigItem with redefined search,compare
methods.
I left all these tasks fore the second iteration :)

:(
If we are talking about config, I thought about another 2 things:
1. stronger syntaxis.
I mean avoid stupid typo: "max_dic_size" instead "max_doc_size"
2. Usage in conf.[yl] String class instead char*.
