Create custom event

As the title suggests, is it possible to create a custom event that can be used as a script?

You can't register a custom event but you can

Code:

frame:GetScript("OnEvent")(frame, "my_custom_event", somerarg)

Ok, I can save a function like this

Lua Code:

local func = frame:GetScript("OnEvent")(frame, "my_custom_event", somerarg)

Then how can I use the function? Via func() of course, but where and how?

So, not an event but a frame method (function)

Lua Code:

function frame:SomeFunc(arg1, arg2)
    self:SetAlpha(arg1)
    if arg2 == "something" then
        -- do other stuff
    end
end

Code:

frame:SomeFunc(0.5, "something")

You can also use a Mixin to apply methods but that ends up being the same thing.

I've created a fairly elaborate frame in XML, which inherits a template. Since writing

Code:

<OnLoad>

    -do stuffs

</OnLoad>

override the template's OnLoad scripts, I was wondering if it was possible to create a custom event.
There is a solution: rewrite the frame code in Lua, but that would be quite cumbersome. Some time ago I read about a little program that converts XML to Lua: does it still exist?

Otherwise, what solutions do you recommend?

In order to avod wall text, this is my frame coded in XML: https://tinyurl.com/ytmwmbt4, from line 52 to line 72

Lua Code:

<OnLoad inherit="prepend">
    -- do stuffs
</OnLoad>

Will allow the template's OnLoad to run. There's also inherit="append" if processing order is critical.
