Well... table.concat works "Given an array where all elements are
strings or numbers"... nil is neither a string nor a number...
http://www.lua.org/manual/5.1/manual.html#pdf-table.concat
So...
local aList = { 1, 2, nil, 4 }
-- works
print( table.concat( aList, '/', 1, 2 ) )
-- raises an exception
print( table.concat( aList, '/', 1, 3 ) )
In other words... go with the flow... not against it :)
