Any character inside any variable name can be eaten too,
and horrible thing (global variable is used instead of local one)
happens.
Nevertheless you can live happily with it.
Closing "end" of some block (for-end, do-end, function-end)
could be eaten too, and Lua raises error
"'end' expected near ..."
without giving you a knowledge about the line#
where the error actually happened.
Usually error message points to the very end of your file.
Nevertheless you can live happily with it.
The situation with apostrophe been eaten does not introduce
"horrible things" which previously do not exist in Lua.
