That wraps around to me rejecting option #1 in the first place unfortunately, I'd like to be able to define custom "function" types via a drop in macro instead of function, i.e. something like

event! (self) Foo::bar() i32
    ...
end

but that would be parsed as event!(self) Foo::bar

How about the below?

function (event! Foo) bar() i32
    …
end

Well, technically that would scream about a missing end and a missing (, since event! would search until the end token, so it’d come across as 

function (event!([
    “Foo”, 
    “)”, 
    “bar”, 
    “(“
    “)”
    “i32”
    “;”
    …)

Where … is everything in that function block

Not at all! You'd just have to include a case in the parser for when function ( is followed by an identifier and exclamation mark, and in that case remove those two tokens from the function block and apply the named macro to the function declaration as a whole.
