This information applies to the PICO-8 0.1.6 release.
This document is here to help folks with a proficiency in Lua understand the limitations and discrepencies between Lua and PICO-8's Lua.
You can always view the manual or yellowafterlife's extended 0.1.1 manual.
print(function() end) outputs the string function instead of the string function: 0x0000000.
