In Lua, the first is 4301 and the second is a runtime error. ('1' .. 4301) is 14301, the equivalent of the weird thing Python is fixing would be spelled `tonumber(('1'):rep(4301))` which is obviously wrong. To my taste operator overloading is fine, but concatenation isn't addition, so they shouldn't be overloaded because... [gestures vaguely at a half dozen language]
