Previously we would insert new (Arrow)FunctionExpressions as a sibling
of the original function. However this would break in the outlining case
as it would cause the original function expression's parent to become a
SequenceExpression, breaking a bunch of assumptions in the babel plugin.
To get around this, we synthesize a new VariableDeclaration to contain
the newly inserted function expression and therefore insert it as a true
sibling to the original function.
Yeah, it's kinda gross

React Compiler
React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.
More information about the design and architecture of the compiler are covered in the Design Goals.
More information about developing the compiler itself is covered in the Development Guide.
