The purpose of `spurt` is to:
1. open a NEW file to write to
2. print a single string
3. close the file
If you are calling `spurt` more than once on a given file, you are doing it
wrong.
If you give `spurt` an array, you are probably doing it wrong; unless you
want the array turned into a single s
Hi All,
Just out of curiosity, why is the \n printed out literally here?

You are forgetting that spurt comes with an `:append` option.

The <…> and «…» constructors break on whitespace.
So will actually produce the following array:
["a,b,c,d,e,f"]
It's only one item. If we placed space after the comma, that is, , you'd get a six item list, but with the commas attached to all but the
final:

Actually no I'm not “forgetting that spurt comes with an `:append` option”.
That is a slightly different use case.
It is where you are appending to an existing file once, and then never
touching it again.
(Or maybe you might be touching it again in a few hours.)

Note that :single means it acts like single quotes.
Single quotes don't do anything to convert '\n' into anything other than a
literal '\n'.
If you want that to be converted to a linefeed you need to use double quote
semantics (or at least tur
