RE: Wrong number of elements in stack ...

["Milano Carvalho" <milanogc@...>]

It is normal. When a function returns multiple values they will be printed 
out only if this function was the last to be called.

Example:

function f() return 1, 2, 3 end
print(0, f())
-> 0, 1, 2, 3
print(f(), 4)
-> 1, 4
