But now what if the argument sep doens't really matter to me as it doesn't really affects the result besides a changed seperator.\r\nIs there a way to exclude it so that there will be only a new cache if a or b changes and not sep?\r\nOr if not will this be a feature in an upcoming version?\r\n\r\nThanks in advance for help"},"comment":{"url":"https://api.github.com/repos/r-lib/memoise/issues/comments/449493704","html_url":"https://github.com/r-lib/memoise/issues/54#issuecomment-449493704","issue_url":"https://api.github.com/repos/r-lib/memoise/issues/54","id":449493704,"node_id":"MDEyOklzc3VlQ29tbWVudDQ0OTQ5MzcwNA==","user":{"login":"dapperjapper","id":246279,"node_id":"MDQ6VXNlcjI0NjI3OQ==","avatar_url":"https://avatars1.githubusercontent.com/u/246279?v=4","gravatar_id":"","url":"https://api.github.com/users/dapperjapper","html_url":"https://github.com/dapperjapper","followers_url":"https://api.github.com/users/dapperjapper/followers","following_url":"https://api.github.com/users/dapperjapper/following{/other_user}","gists_url":"https://api.github.com/users/dapperjapper/gists{/gist_id}","starred_url":"https://api.github.com/users/dapperjapper/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/dapperjapper/subscriptions","organizations_url":"https://api.github.com/users/dapperjapper/orgs","repos_url":"https://api.github.com/users/dapperjapper/repos","events_url":"https://api.github.com/users/dapperjapper/events{/privacy}","received_events_url":"https://api.github.com/users/dapperjapper/received_events","type":"User","site_admin":false},"created_at":"2018-12-21T20:43:22Z","updated_at":"2018-12-21T20:43:22Z","author_association":"NONE","body":"Referencing #75 because I believe these are the same idea.
