Come on! He's guilty of not posting the code ( where I could easily
find it, because AFAIK he could be using getc() equivalents on ruby ).
I consider tcl version better or equal than lua.

If he is using gets, which discards the newline and seems the more
probable, he is reading hello=5+nul=1+world=5, if he is using another
function

If he is not and the count includes the newline, then TCL is getting
all the 'text file legal' chars plus the line count right, lua does
not get even the line count. In this case ( which I doubt is the one
happening ) they could be considered on par ( both wrong ) or better (
some things right ( text chars, line count ) in TCL nothing in lua ).
I do not see how it may be considered worst ( unless you argue the
more wrong the better as it is easier to spot ).
