What's your mean by saying this? Sorry for my poor English.
"No 'magic'" (魔法 if Google is to be trusted :-) means here that there is
nothing complicated and strange going on in the background.
"STREAM.isatty()" just asks a question -- is this a tty? -- and the
answer will always be the same for the same STREAM. Either it is a tty
or it isn't, it will not change from one to the other. It's exactly
like "STRING.isnumeric()"; for the same string it will always give the
same answer.
