They _are_ bad if '+' is overloaded to mean both concatenation and
addition, as in JavaScript.

For Lua, the coercions in a..b and a+b are pretty well defined, but of
course they may throw an error, and that's when explicit
tonumber/tostring is useful.

Even strong typed languages know the wisdom of automatic coercion to
string when the context demands it (e.g. string + in Java)
