The following program freezes PICO-8 0.11.g (probably an infinite loop in the parser), even Esc will not work:

x=2b

The bug does not only happen with invalid code, here it is with valid Lua5.2 code:

x="\
2b"

or this:

x=[=[
2b
]=]

Even typing "2b" in the command prompt freezes everything.

lol confirmed that this is indeed a thing.

good catch, @samhocevar

It's been fixed for 0.1.12, according to zep.

Oops, sorry for the duplicate then! Will mark this as fixed.
