+/**
+ * Edge 16 & 17 do not infer function.name from variable assignment.
+ * All other `function.name` behavior works fine, so we can skip most of @babel/transform-function-name.
+ * @see https://kangax.github.io/compat-table/es6/#test-function_name_property_variables_(function)
+ *
+ * Note: contrary to various Github issues, Edge 16+ *does* correctly infer the name of Arrow Functions.
+ * The variable declarator name inference issue only affects function expressions, so that's all we fix here.
+ *
+ * A Note on Minification: Terser undoes this transform *by default* unless `keep_fnames` is set to true.
+ * There is by design - if Function.name is critical to your application, you must configure
+ * your minifier to preserve function names.
