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 string first.
`spurt` is the dual of `slurp`.
The purpose of `slurp` is to:
1. open an existing file to read from
2. read the whole file into a single string
3. close the file
That is they are only short-cuts for a simple combination of operations.
If you are opening a file for only the express purpose of reading ALL of
its contents into a SINGLE STRING, use `slurp`.
If you are opening a file for only the express purpose of writing ALL of
its contents from a SINGLE STRING, use `spurt`.
If you are doing anything else, use something else.
---
Assuming you want to loop over a bunch of strings to print to a file, use
`open` and `print`/`put`/`say`.
This is also faster than calling `spurt` more than once because you only
open and close the file once.
If you want there to be only one call, turn your array into the appropriate
single string first.
