Survey and analysis of TC39 proposals by nature

I just thought I'd get some hard numbers on TC39 proposals, so I went through all the proposals listed at the GitHub - tc39/proposals: Tracking ECMAScript Proposals repository and categorized them according to whether they have semantic nature (defined as: they specify a change detectable by code at runtime), syntactic nature (defined as: cannot be polyfilled without a change to the engine), or both. I've uploaded it as a gist here:

I've rather arbitrarily defined stage 2+ proposals as "Successful" and stage 1- proposals as "Unsuccessful", on account of U comes after S, both of those come after E, and I wanted the document with the totals to appear first in the list.
