Can you assign a function's type with 'function table:method()' syntax?

[7z99]

I'm wondering if it's possible to assign a function's type when the function is a member of a table using function:method() syntax?

Basically, from what I know, the only way to assign a function's type when the function is a member of a table is the following:

local t = {}
t.func = function()
	
end :: typeof(otherFunc)

The problem with this is that it just isn't nice to look at, especially when/if I need to use a colon to call the function, I would need to do something like:

local t = ()
t.func = function(self, arg1, arg2)

end :: typeof(otherFunc)

instead of this, which is the desired syntax, but it is not valid:

local t = {}
function t:func(arg1, arg2)

end :: typeof(otherFunc)

So, is there a way to assign a function's type with using the desired function table:method() syntax?
