> BTW, I could easily be wrong, but I think C behaves the same way as Python.

C syntax has many traps that are much better out of modern languages
like Python/D/etc.

I think C has that feature because it lacks an operator for string
concatenation, while both Python and D have one (+ and ~. D uses the ~
to avoid any programmer confusion with the mathematical summing
operator), so the situation of Python/D is different.
