overlookmotel 48e20880d4 perf(ast): box enum variants (#3058) ... Box all enum variants for JSX types (`JSXAttributeName`, `JSXAttributeValue`, `JSXChild`, `JSXElementName`, `JSXMemberExpressionObject`). Part of #3047. I'm not sure how to interpret the benchmark results. As I said on #3047: > I imagine it may cost a little in performance in the parser due to extra calls to `alloc`, but in return traversing the AST should be cheaper, as the data is more compact, so less cache misses. Sure enough, there is a small impact (1%) on the 2 parser benchmarks for JSX files. However, the other benchmarks have too much noise in them to see whether this is repaid in a speed up on transformer etc, especially as the transformer benchmarks also include parsing.
