I think more serious objections are following:
1. The parser would be complicated if some nested structure was
allowed that could use the delimiter ',' - e.g.:
local x: {name: string, age: integer} = 0
Of course Ravi doesn't allow this but others might.
2. The proposed approach doesn't allow for function return parameters
to be annotated.
3. There could be a requirement to declare types outside of local
statements or function parameters.
So I withdraw my suggestion as it is too limited in scope - and won't
really be generic enough.
