• [ ] GopherLua is a Lua5.1 implementation. In Lua, to keep it simple, it is more important to remove functionalities rather than to add functionalities unlike other languages . If you are going to introduce some new cool functionalities into the GopherLua code base and the functionalities can be implemented by existing APIs, It should be implemented as a library.

Please answer the following before submitting your issue:

1. What version of GopherLua are you using? : 0.0.0
2. What version of Go are you using? : 1.14.1
3. What operating system and processor architecture are you using? :windows
4. What did you do? : =====main.lua==== require "bug" bug.conver("main") ============== =====bug.lua===== module(..., package.seeall) function conver(str) str = f() and str or str print(type(str)) end function f() return false end ================
5. What did you expect to see? : string
6. What did you see instead? : boolean

function conver(str) str = f() and str or str print(type(str)) end function f() return false end conver("main")

I've found out that if you don't reassign to the "str" variable it works as expected. Like this:

function f()
	return false
end
function conver(str)
	str2 = f() and str or str
	print(type(str2))
end
conver("main")

I guess there must be a bug in handling self-assigning expressions. Indeed weird!
