I'd just use boost::cnv::spirit and specify explicitly what happens when
conversion didn't work... much shorter, very well optimized (the best) when
it does work (the conversion)...

There's more than servers in life. Handling f.e. O-O-M-situations is not
gonna help me on my lap-top... a re-think and re-write of my app is in this
case in order, though... or a trip to the shop and buy a bigger stick (both
the "slow path").

Yeah, that's another discussion, isn't it? errors vs. exceptions. Should
exceptions be exceptional, or getting back to your conversion example,
should we use exceptions to indicate failure as this is the case in
Boost::Lexical_cast? I know the answer I like best, and moved on to
