Hi Luiz, is there any plans to support <toclose> and <const> (i.e. the
annotation syntax) on the function parameters?
e.g.
function foo(<tobeclose> f, <const> cfg)
-- use f and cfg
end -- the f will be close and cfg can not modify in the function body
the most way to use "const" in C is use it as function parameter
qualifier. So does Lua plan to support it?
Lua is nice in that it supports shadowing. So you can just do:
function foo(f, cfg)
local <tobeclose> f = f
local <const> cfg = cfg
end
P.S. the new syntax is ugly, indeed :-(
