Make const implicitly typed

[hdadr]

Just like how var works, i would like to use const similar way.

For example:
const int x = 10; ->
const x = 10;

const double pi = 3.14; ->
const pi = 3.14;

Edit: The purpose of this idea is to eleminate the unnecessary type declaration.

Isn't it a better idea to allow the keyword var in const?

[hdadr]

The idea behind making const implicitly typed is to eliminate type declaration which i find unnecessary.
I feel var also unnecessary here.

I think it would make the code less readable.

Coming from typescript background, for me using this way eleminates some "noises", so it makes more readable.
