1. Lua will look more like C.

2. The Lua syntax definition will have been bloated, and someone will 
have needed to spend a lot time on implementation, merely so that
we can type 

    a = b = c = d = e = math.pi

instead of 

    a,b,c,d,e = rep(math.pi,5)

where 'rep' is defined earlier as 

-- Lua 5.1 code
function rep(a,n) local t={} for i=1,n do t[i]=a end return unpack(t) end
