Hi all,
This is an extended version of David Manura's globalsplus.lua
described in http://lua-users.org/wiki/DetectingUndefinedVariables
Here is a fragment culled from a program:
------------------------------
local opts={}
if opts["h"] then
os.exit ()
end
if not opts["gogo"] then
end
------------------------------
It gives me:
$ lua globalsplus.lua t.lua
globals: t.lua:5: undefined get os.exit.gogo
If I remove the second "if", everything is ok.
Is that interesting?
