Re: __declared

[Graham Wakefield <wakefield@...>]

I may be missing something, but a routine to print all globals is 

for k, v in pairs(_G) do
	print(k, v)
	-- insert recursion if desired here… 
end

(Obviously a fancier printer would memoize, handle loops, trace metatables, format prettily etc… but my point is that strict.lua isn't required to find globals.)
