So fish doesn't make a distinction between line separators and field
separators in IFS? I hadn't expected that, it treats \n and spaces quite
differently.
I have had the need to join array elements before, but I've always used a
strjoin-like function (but a sane variant instead of the one from my first
message, though the sane one doesn't work with \n currently). I'd say an
explicit function (possibly shipped with fish) is better/more explicit than
magic IFS trickery.
The current behaviour of joining "$var" with spaces is however a bit
arbitrary, so I'm not against having it configurable with $IFS. However I
would prefer having it join with spaces by default, somehow "$var" being a
single line string rather than a multiline is more what I would expect, and
so would bash users probably.

All the data continuously generated in your IT infrastructure contains a
definitive record of customers, application performance, security
threats, fraudulent activity and more. Splunk takes this data and makes
sense of it. Business sense. IT sense. Common sense.
