It would be nice to be able to use $HOSTALIASES like:

foo 10.10.10.10

And not only:

foo bar

Correction: it does work, but not for all the commands (ping, autofs does not resolve the aliases, curl and firefox do).

@andrei-dobrea, someone who actually knows what he's talking about should answer this. But IIRC some of those have their own resolution libraries. That's why.
