This is more concise and ruby does a better job performance-wise. This used to be `bsearch_index` already but ruby@6d8358c changed it. ruby#1733 (comment) said: > Yeah the edge case was that the value matched an element exactly But surely there would be a test to show this behaviour? Gets called as part of pretty-printing nodes. Further reduces the time for `SnapshotsTest` by ~16% for me.

If I recall correctly, it was getting the wrong line number when the bounds of the node hit the newline exactly. I think maybe heredocs were the issue? I'm surprised to see none of the snapshots change though. I'm going to optimistically merge this and hope things are fine assuming this is good. |
