I have an idea.
Strings can be treated as integer numbers of arbitrary length.
So, a string of length 8 can be used instead of 64-bit integer.
Let all integer and bitwise operations be implemented on strings.
Strings will never overflow because of auto growing up.
It will be cool to have very-long-integer arithmetic in Lua
without external libraries.
