Programmer Humor

Your argument isn't making me any happier - it just fills me with more rage.

That's slightly misleading, I think. There are no arrays in Lua, every Lua data structure is a table (sometimes pretending to be something else) and you can have anything as a key as long as it's not nil. There's also no integers, Lua only has a single number type which is floating point. This is perfectly valid:

local tbl = {}
local f = function() error(":(") end

tbl[tbl] = tbl
tbl[f] = tbl
tbl["tbl"] = tbl

print(tbl)
-- table: 0x557a907f0f40
print(tbl[tbl], tbl[f], tbl["tbl"])
-- table: 0x557a907f0f40	table: 0x557a907f0f40	table: 0x557a907f0f40

for key,value in pairs(tbl) do
  print(key, "=", value)
end
-- tbl	=	table: 0x557a907f0f40
-- function: 0x557a907edff0	=	table: 0x557a907f0f40
-- table: 0x557a907f0f40	=	table: 0x557a907f0f40

print(type(1), type(-0.5), type(math.pi), type(math.maxinteger))
-- number	number	number	number

PHP did that same thing. It was a big problem when algorithmic complexity attacks were discovered. It took PHP years to integrate an effective solution that didn't break everything.

I always felt that Lua was a girl

Apple Basic (on an Apple IIe) was my first language that I recall.

Didn't have a computer powerful enough for VB until later. It does have a special place in my nostalgia zone but has also led so many astray.
