if u want to say one-hundred-twenty-three u would not think, that C understands
"1 23"...
I feel like "-123" and "- 123" are not quite the same...
That feels more natural to me...
But I noticed that it was quite tricky to teach flex&bison the difference
between sign and unary-inversion-operator... 😋

Maybe this example demonstrates a use: "123" is usually not the same as "12Â Â Â Â Â
        3"...
Maybe something like "1 234 567" might be used in newspapers for "1234567",
but the professional typesetters use special space symbols then,
which are thinner and they stick hard to their neighbors,
so that a newline is impossible at them... 😋
