Lua handles string concatenation quite well. I long chain of `..' 
operations will just emit a series of register loads followed by a 
single CONCAT opcode.

On the other hand, string.format has the %q option which makes it safer 
for building strings that will be compiled. Perhaps this is what Joao 
was implying. Doing `code = "'" .. some_string .. "'"' invites arbitrary 
execution if some_string isn't properly protected.
