#7222.\r\n\r\nBefore we did not special case binding patterns when serializing a type, and just tried to write then as parameter names, that resulted in getting the string of the node, which may contain initialization/references to local variables, etc..This change adds special handling for binding patterns in signatures. \r\n\r\nNote we could just emit the name as a temp variable, but adding the full context seems more user-friendly and is inline with what we do in the declaration emitter (when we are serializing nodes instead of serializing inferred types in here).","created_at":"2016-02-24T21:25:33Z","updated_at":"2016-02-25T21:38:55Z","closed_at":null,"merged_at":null,"merge_commit_sha":"a4f6b1a809e63518ac7d3300169373a4e0c81486","assignee":null,"milestone":null,"commits_url":"https://api.github.com/repos/Microsoft/TypeScript/pulls/7226/commits","review_comments_url":"https://api.github.com/repos/Microsoft/TypeScript/pulls/7226/comments","review_comment_url":"https://api.github.com/repos/Microsoft/TypeScript/pulls/comments{/number}","comments_url":"https://api.github.com/repos/Microsoft/TypeScript/issues/7226/comments","statuses_url":"https://api.github.com/repos/Microsoft/TypeScript/statuses/87a00c30f6701aef173dfd602dcc28f2e73cde33","head":{"label":"Microsoft:bindingPatternsInTypes","ref":"bindingPatternsInTypes","sha":"87a00c30f6701aef173dfd602dcc28f2e73cde33","user":{"login":"Microsoft","id":6154722,"avatar_url":"https://avatars.githubusercontent.com/u/6154722?v=3","gravatar_id":"","url":"https://api.github.com/users/Microsoft","html_url":"https://github.com/Microsoft","followers_url":"https://api.github.com/users/Microsoft/followers","following_url":"https://api.github.com/users/Microsoft/following{/other_user}","gists_url":"https://api.github.com/users/Microsoft/gists{/gist_id}","starred_url":"https://api.github.com/users/Microsoft/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Microsoft/subscriptions","organizations_url":"https://api.github.com/users/Microsoft/orgs","repos_url":"https://api.github.com/users/Microsoft/repos","events_url":"https://api.github.com/users/Microsoft/events{/privacy}","received_events_url":"https://api.github.com/users/Microsoft/received_events","type":"Organization","site_admin":false},"repo":{"id":20929025,"name":"TypeScript","full_name":"Microsoft/TypeScript","owner":{"login":"Microsoft","id":6154722,"avatar_url":"https://avatars.githubusercontent.com/u/6154722?v=3","gravatar_id":"","url":"https://api.github.com/users/Microsoft","html_url":"https://github.com/Microsoft","followers_url":"https://api.github.com/users/Microsoft/followers","following_url":"https://api.github.com/users/Microsoft/following{/other_user}","gists_url":"https://api.github.com/users/Microsoft/gists{/gist_id}","starred_url":"https://api.github.com/users/Microsoft/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Microsoft/subscriptions","organizations_url":"https://api.github.com/users/Microsoft/orgs","repos_url":"https://api.github.com/users/Microsoft/repos","events_url":"https://api.github.com/users/Microsoft/events{/privacy}","received_events_url":"https://api.github.com/users/Microsoft/received_events","type":"Organization","site_admin":false},"private":false,"html_url":"https://github.com/Microsoft/TypeScript","description":"TypeScript
