Re: [proposal] A statement that can return value (and can used in expr)

Lua 5.1 will create a new closure every time this statement is execute.
Lua 5.2 will not: it will resuse the closure.

Try the code below in each version:

for i=1,3 do
        local f = function(a, b) print "a statement" return a + b end
        local a = f(10, 20) + 30    + i
        print(f,a)
end
