This special case exists for literal strings and table
constructors to make Lua more flexible as a data-description
language:
local CeeStr = c"Hello"
local FourthChar = CeeStr[4]
local RectObj = r{x = 20, y = 20, height = 20, width = 20}
RectObj.Paint()

As mentioned before, the colon has its advantages. Whether
those advantages are worth the extra complexity is a
judgement call, one on which I agree with the Lua authors.
(I don't think Lua is in much danger of becoming bloated.)

All of the libraries, including io, use the dot notation.
The io library (the only library that deals with handles)
also uses the colon notation when a handle is involved.
