For another options, reuse behavior is known. But not for full set in combination with particular
set. It is inconvenient.
Sometimes it is need to get one value quickly without parsing at the others (for example, for
debugging and screen output – one line but not dozens).
Such a combination can simply be wrong. How does the program respond to an input error?

If there are multiple lines, how do I find the last one? Where is the beginning and where is the end
of the JSON object? What is the «JSON object» in terms of «MS PowerShell»? There is a string and an
array of strings. There are no «JSON objects». Test youself the property «.GetType()» of curl output
and be sure.
An what is the «JSON object» in «MS Cmd.exe»?
