Hi Kurt,
Method overloading and operator overloading are the two ways you can do this.
Adhoc overloading of unqualified function names was considered as part of the design of F#. However, we rejected it on software engineering grounds.
As you would appreciate, adhoc overloading can be a blessing and a curse. In C# and .NET overloading is relatively "tamed" primarily because all references to overload sets are qualified by a type name, e.g. C.M, rather than just M (except in the body of C, which is somewhat different). In F# we chose to follow a similar approach: permit method overloading, but ensure that references to overloaded things are qualified by (type) names. We expect this restriction to continue.
This may mean that you either use members more than you might otherwise to implement your overloading, or that you may need to add a few more calls on the client side of a library to distinguish between the three cases you mention.
Kind regards
don

Is there a way to overload functions (or simulate it someway) in F#? For example, I want one function (or three different functions with the same name) that can take a bool or a Lazy bool or a Property (my type) and have it return a Property.
I've tried:
-) static member overloads, but that only works if arguments are tupled, so I can't use pipelining operators and the like. Also members can't be infix.
-) Operator overloading, but I can't seem to get that to work as I want it. Using traits it is possible to supply an operator implementation on a type that I implement, but not on existing types (i.e. traits don't detect augmentations).
Any other options/ideas/voodoo I could try?
cheers,
Kurt
