If you work on this, would you mind moving the expressions to their own folder? Right now they're in compiler/common, but it would be better if they were moved to compiler/expression.

@dicarlo2 can we can close this issue now?

Thanks once again for all your help! You did a great job here... I barely had to give any feedback.

Yea, I'm pretty sure this is complete, if I missed any I'll open another issue.

Thanks again for the speedy reviews!

Cool, this is now released in v5.5.

By the way, fun fact: Node.d.ts is over 15,000 lines long since there's so many new wrapped nodes... the release took 10 minutes to run in order to generate all the overloads (ex. getFirstChildIfKind(kind: ts.SyntaxKind.Block): compiler.Block | undefined;). I think I'm going to make the js docs a single line. Also, in the future I'm going to need to work on improving the performance so that it's a bit quicker when working on large files.
