This is very cool! I'm curious if it'd be relatively straightforward to use Fennel‡ with MicroLua? ‡ https://fennel-lang.org/

MicroLua currently compiles Lua files to binary at built time. It seems that Fennel is capable of transpiling to Lua source code, so it should be easy to add that step to the build process.

I can't get my head around a 1 based language.

Normally education or human oriented languages start arrays at 1 (Smalltalk, Cobol, Lua, APL, Wolfram, etc) while hardware oriented languages start arrays at 0 (C and friends, Oberon, Forth, Scheme and so on). Human oriented languages that have to play nice with C also tend to use 0. As do Python and Basic, which contradicts my rule.

Probably the number one reason not to start arrays at 0 in an educational language is that having the last element of an array of size 10 have an index of 9 causes quite a bit of confusion.

FTR, Fennel support was indeed fairly easy to add.

Whoa — that's amazing!
