I think allowing to omit parentheses around string literals for method calls on them would be nice.

It would be useful:
   s = " ":rep(10-#s)..s
   n = n*10 + digit:byte() - "0":byte()
   n = n*16 + "0123456789ABCDEF":find(hex_digit:upper()) - 1
   x = "<d":unpack("<I4I4":pack(n1,n2))
I'd also like indexing literal tables:
   RGB = {red=0xFF0000, green=0x00FF00}[color_name]
   if not {["Lua 5.2"]=1, ["Lua 5.3"]=1}[_VERSION] then error"Not supported" end
