It was a complete example with variable and function declarations. A
similar complete example in another language is not likely to be
_much_ more concise, unless you count shortening identifiers.

Overloading can be a useful thing. I just don't think it is be-all,
end-all for the problem space, and I wanted to provide a second way the
task could be done in C besides Charlie Gibbs's "easier to just cast"
method.

I've been doing some Arduino programming recently, and while I'm writing
C, it's clearly C++ overall because of the libraries I'm using, some of
which are overloading stuff. One of those does things I find awkward
because it tries to invoke the int method at times I don't want. Eg
it wants zero to be the ASCII zero instead of ASCII null unless I write
it as "byte(0)".
