While

x=myObject.myMethod(theParameter)

is cleaner syntax than

x=call_method(myObject,"myMethod",{theParameter})

as is correct Diamond syntax, the latter is hardly unusable.

I am putting the finishing touches on Diamond 3.0, with many improvements.
My next project will be a preprocessor enabling dot notation.

I need to figure out a notation for events--in Diamond, events are not
properties or methods, they are a third thing.

x.y=z   means set_property(x,"y",z)
x=y.z   means x=get_property(y,"z")
x=y.z() means x=call_method(y,"z",{})

What would be good notation for
link_handler(x,"y#1",z) and raise_event(x,"y",{z}) ?

(The "y#1" in link_handler is because events can be overloaded based on the
number of parameters--it is needed because x might also have a y#0 or y#2
event.)

I'm leaning towards

x!y(1)=z   and   x!y(z)

Any suggestions?
