TypeScript Version: 2.0.0-dev.20160628 (the same error in all older versions)

Code

function test(a: string, b: {}, c: number) {}

test('one', {}, 3); // OK

let params = ['one', {}, 3];
test(...params); // ERROR

Expected behavior:
The destructured array should resolve to the same types for each of the parameters and should not give an error.

Actual behavior:
Error:

Supplied parameters do not match any signature of call target.

Looks like a dupe of #5296.
