  I can't give an objective reason, but for me, using sigils for scope
(which is what Ruby does if I recall correctly) triggers my aesthetic
sensibilities.

  Anyone can get used to anything [1], thus the subjectivity.

  I've used luacheck to find typos and inadvertant globals.  It's easy to
use, and if you use some form of source control, most give you a way to run
scripts prior to code checkin, so you could have the checkin fail if
luacheck finds an issue.

  Does it suck to have to use another tool?  I don't know.  For me, it's
worth it.
