Homoiconic. Generates zero-dependancy Lua for LÖVE, Playdate, or standalone Lua 5.4.
One evaluation rule. One data structure. One scoping mechanism. The whole model fits in your head.
Type mismatches error. Money uses cents, not floats. No silent corruption.
No implicit coercions. No operator precedence. Assignment by reference; copy when you mean it.
From "Hello, World" to a full game dialect.
