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).
