My solution is bad because of two reasons: "-i" means one can't just
run Lua scripts.

Your solution is bad because those nine functions are only accessible
via package.loaded.math. (My solution is bad because of that too.)

My current solution still uses an alias, and my be bad because of
other reasons, but at least it solves those.

alias lua='LUA_INIT="setmetatable(math,{__index=require[[mathx]]})"
/usr/local/bin/lua'
