If I have a function with parameter param: () -> Boolean how can I call this function using method reference Foo:myFunction as a parameter?

[diesieben07]

What's Foo here? A class?

[Jukka Siivonen]

Good question, interface actually

[diesieben07]

Then your param either needs an instance parameter or you need to do someFooInstance::myFunction

[Jukka Siivonen]

The actual use case is that I need to call this function in two places, other just () -> true and other using Foo:myFunction

[diesieben07]

Well Foo::myFunction is of type Foo.() -> Boolean, it needs the actual instance of Foo to call the method on.

[diesieben07]

If you want () -> Boolean you need to pre-bind the receiver: myInstance::myFunction

[Jukka Siivonen]

ah, correct, forgot about that.
