[Wikidata-bugs] [Maniphest] [Commented On] T145138: Wikibase Lua API have breaking change

[hoo]

hoo added a comment.

If we change the metatable in the above example to the following, string concatenation will work:

setmetatable( definition, { __index = Label, __tostring = function( self ) return self:toString() end, __concat = function(t, str) return tostring(t) .. str end } )

But still for example the length operator (#label) wont correctly work.
