Reading the bash documentation, it seems that the history builtin in
bash doesn't really do anything that isn't easily done either using
array splicing or a simple pipeline. But it makes a lot of sense to be
Posix compatible whenever the alternative isn't significantly better.
Maybe that is the way to go. If the (foo)[2 4] syntax doen't seem to
have any side issues, then I guess there aren't really any advantages
for $history other than slightly less code to implement it.

Lots of them. grep. expr. sed. ;-)
All history items where grep is called but not less:
printf "%s\n" $history|grep sed|grep -v less
It would be really easy to provide this type of functionality built
into fish through some magical ([{\{REGEX\}}]) syntax, like e.g. bash
does, but what would be the point? Save maybe three key strokes, and
lose the consistency and small size of the language.

Yay! :-)
Does that mean I will be getting a completion file for SBCL?
