I see. I guess that illustrates how hard it can be to understand a lot of
I was thinking that just by extending the Lua syntax
table::function() -> methods(table):function()
That way the new colon syntax is related to the old mnemonically. From the
C++ perspective your way makes sense, but I don't think asking people to
remember syntax with reference to C++ is a good thing.
Too bad .. is concatenation or you could use t..x and t::x to mean
methods(t).x and methods(t):x respectively.
