Turns out this is a problem with our Lua parser.

The problem occurs when you use goto as the key in a table expression:

local x = { goto="foo"}

goto is a keyword in Lua 5.2 (and a reserved name before then) so it shouldn't really be used like this, but our grammar struggles with such expressions, and luajit happily allows goto in tables, while vanilla lua doesn't.

A workaround is to replace usages of:

goto = ...

in table literals with

["goto"] = ...

We will be looking into a proper fix for this.
