I should make a library for this that doesn't require debug.

Maybe something like "local f = mkgetter("a", "b", "c", ...)" or "local 
f = mkgetter().a.b.c()" and then "if f(obj) then", maybe even return the 
depth as a second return so like local value, depth = f(obj), depth 
could be negative if the second arg was true as in f(obj, true).

It obviously won't use pcall as that's slow. Might use tail calls 
because I love tail calls. :P
