TypeScript Version: 2.5.2 / nightly (2.6.0-dev.20170922)

Code
tsconfig.json with noImplicitAny set to true:

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "strict": true,
    "noImplicitAny": true
  }
}

Creating a variable without specifying a type:

let i;
i = 5;
i = "foo";

Expected behavior:
Typescript compiler complains that i is implicit any.

Actual behavior:
Typescript compile does not report any issue.

If I use typescript 2.0.10 (with adapted tsconfig.json) I get "error TS7005: Variable 'i' implicitly has an 'any' type." as expected.

   Ah ok thanks, thats fine.
   Seems I got confused by VsCode which shows let i: any if I hover my mouse pointer over the statement i = 5.
