Show catch and show function name

[Adelin Berard]

Hello, I found two case that are not handled correctly

• Catch block are ignored
  
• Some argument block don't show the parenthesis function name

I opened a PR for this :)

Some argument block don't show the parenthesis function name

Note that i did not cover the this because it's not a regular statement or function expression. I'll see about this in another PR because it's probably language specific.

Edit: Indeed it is. In ts/js for example this is not available via a distinct node type.
