Also, if the number is used as a key to table, there's no implicit conversion. Such bugs are tedious and hard to find.

Hrm. Yes, you're right. That's annoying.

How horribly would it break things if you made <string> == <number> implicitely attempt to convert the string to a number? And what about changing strings so that hashing a string that contained a number produced the same value as hashing a number?

...although, thinking about it, this could well be a pretty ghastly idea, too.

The problem with changing string.find() to return real numbers is that it doesn't know when you expect to find a number or not. Which means that it will fail for all the reasons that the above two suggestions will fail.

local _, _, a, b = string.find("42.00000000000000000000000001 world",
print(a == 42)
--> ?
