Code

declare const foo: string;
console.log(foo);

tsc -t es5 --strictNullChecks ./foo.ts

Expected behavior:

Compiles.

Actual behavior:

foo.ts(2,13): error TS2454: Variable 'foo' is used before being assigned.

Allowing foo to be undefined makes it compile, but this shouldn't be required of course.

declare const foo: string | undefined;
console.log(foo);
