Missing information

Description

The section on Optional Arguments speaks only about the form used for interop with C#. However, the F# language supports an entirely different mechanism, which is not covered by this article. For details, c.f. F# Language Specification, § 8.13.6. This is a very common technique, and it's exclusion from the documentation is very curious. Also, in the interest of clarity, perhaps it's better to distinguish the two forms with something along the lines of:

• Optional arguments with early defaults (i.e. for C# compatability)
• Optional arguments with late defaults (i.e. missing from the current docs)
