I was looking at some example code and noticed that the author had used extra versions of overloaded functions to achieve what amounted to default values.

eg

foo(int a, int b)
{
    foo(a, b, 5)
}

foo(int a, int b, int c)
{
....
}

were if default values were supported:
foo(int a, int b, int c = 5)
{
....
}

would do the trick.  I appreciate that the compiler may be able to reduce both to almost the same thing, but....

thoughts?

Personally, I like the C++ way of doing it (probably through familiarity over the years), as it seems simple, useful, and less verbose than writing a set of extra functions. But I think Walter may not like it for D.

This has been discussed a lot recently.
