Naming style for generated identifiers

[ChocolateLoverRaj]

Many plugins need to generate identifiers that were not already part of the code. These identifiers need to not conflict with existing identifier names. For example, in Babel, generated identifiers are called _name, and if there is another one, it's called _name2.

Use the same syntax as Babel

Uuids:

• _name
• _name2
• _name3

Pros

• Quickly know that an identifier was generated because it starts with _
• Keep the original name as part of the generated identifier

Cons

• It would be confusing of the original identifier was named var0, because then the generated identifiers would be named _var0, _var02, _var03, which looks confusing
• Need to watch out for a bug with original var names var and var1. They both generate as _var###
