Don't you use '\n'? Surely nobody would say 0x0a?

But, see, nobody in their right mind would say '\012` for that. '\0'
an octal escape sequence like '\012', not a role-based character
abstraction like '\n'.

Actually, it's entirely likely that a programmer using C in 1978
would have used \012 for newline - it was the custom to use octal
on the PDP-11.   Consider the od(1) utility, for example.

But why would they use '\012', if 012 was available. The quotes
and backslash doubles the character count and create visual clutter.

If I want the number 10 of type int, why would I switch into
a character quote inside of which I have to escape back to
a numeric specification.

In C++ it makes sense, because we get the char type, which can
be important:  foo('\012') -> pick the foo(char) overload, not
the foo(int).
