Bar-delimited symbols/strings are especially unsuitable for shell here
strings, because the vertical bar is a common shell character.

The key feature of here strings is that you can choose any arbitrary
sequence of characters as the end-of-string symbol, and you don't need
any "escape" sequences in the string itself.
