Writing a program as you’re learning a dynamic language is like building a house and then walking through it to see which rooms are haunted.

I’ve decided to learn Lua and wow there’s a lot of dangerous ghosts here. I haven’t even started making my own magic tables yet.

Every language is just like every other language except for the one or two weird things. Lua went with “lists are haunted” and I’m excited to see how that works out.

Be really careful wit nil!
The haunted arrays, where the nil element will just cut off the array.

I tried to learn Lua a few years ago when I was in the hospital recovering from my heart transplant. I was so full of drugs that when I got to the tables stuff I just noped out be because I knew my brain was ready to handle it.

The metatable bits are very powerful. I've grown to like it. Just that nil... These errors tend to propagate far before you find the mistake. My Lua code is littered with assert(x ~= nil).
