You can try something like that :
-- Start of Lua ----------------------------
with = function(context)
...
end
endwith = function()
...
end
-- You can then write
with (object) do
name=parent.name..name
end
endwith()
-- End of Lua ------------------------------
Globals can still be accessed directly if not overriden in object, or through _G inconditionnaly. Endwith is the only syntactic drawback, you have to explictly restore the environment. As the do/end is not necessary, you can just write:
with (object)
name=parent.name..name
endwith()
Even that could be encapsulated. Something like:
function withblock (context, function)
with (context)
function()
endwith()
end
used like:
withblock (object, function () name = parent.name..name end)
- Syntax may be a bit rusty, but it's possible to automate the restoration of the environment in this way. I guess maybe the identifier 'function' is not allowed within function, there may be some other caveats too.
