Previously, gonengazit found some infinite token exploits here and zep fixed them, but looks like they're not all gone yet - I stumbled upon one that still happens:

x=[[[[]]
 put your infinite tokens here...
--]]

Seems like it happens because pico8 supports recursive block comments, and uses the same code to also parse long strings recursively.

But lua then parses the long string non-recursively and executes the code that pico8 thought was part of the string.

Pico8 probably should only parse block comments recursively, not long strings.

Ooh, fun! And this one looks even simpler than gonengazit's exploit. Don't tell zep :)
