I have no opinion about whether this one is valuable enough to include in
intarray, but I do feel like sample() is a vague name, and easily confused
with marginally-related operations like TABLESAMPLE.  Can we think of a
more on-point name?  Something like "random_subset" would be pretty
clear, but it's also clunky.  It's too late here for me to think of
le mot juste...
