Feature request: collapse_simple_statement only unnamed functions assigned to variables

[jonasar]

I would like to ask for the feature to be able to collapse all simple unnamed functions assigned to something,
but not declarations of named functions.

Examples

Collapse this
createSomething(5, 2, function() return true end, 3)

local myCallback = function(value) return 2*value end

Do not collapse this
function MyTable:getvalue()
return self.LastValue
end
