Scoped variable attribute syntax

[Dibyendu Majumdar <mobile@...>]

Hi Roberto,

Instead of using something like:

local *toclose var

is it possible to use:

local var :scoped
or
local var @scoped

That the annotation uses either ':' or '@' sign, and follows the
variable name rather than preceding it. Personally I think the
asterisk sign reminds one of C pointers ...

I am thinking of something I had suggested a while back
(http://lua-users.org/lists/lua-l/2015-07/msg00567.html) - i.e.
allowing a way to 'annotate' declarations in a compatible way. That
is, if Lua encounters an annotation, it should ignore if it is not
recognized - that way language extensions can support type annotations
or other types of annotations while still being compatible with Lua.

Thanks and Regards
Dibyendu
