noUnusedParameters doesn't apply to binding elements

[mathias-hansen]

TypeScript Version: 2.0.3

Code

noUnusedParameters flag is set

const f = ([a]) => {};
f([1]);

Expected behavior:
should give an "'a' is declared but never used" error

Actual behavior:
nothing

I believe that this could trigger a get accessor to perform something, but that seems very non-idiomatic.
