Sorry for the late entry, but I just wanted to cast my vote along with
Mark and Rici.
Perhaps there are some subtle side effects I'm missing. I have enjoyed
the benefits of the coercion when I'm typing at the interpreter, but
often that amounts to simple things like:
> print('n = ' .. n)
I would not mind having to type:
> print('n = ' .. tostring(n))
Wouldn't the __concat metamethod for strings handle that, though?
