Misusing the proc macros gives poor error messages

[Demi-Marie]

Misusing the proc macros results in very unhelpful error messages. I have seen:

• Unwrapping None
• Undefined variables with no explanation
• Probably others

Furthermore, the correct use of the proc macros is poorly documented. I had to figure it out by trial and error.

Can you elaborate on what kind of documentation would be useful to you and how the error messages can be improved? Contributions are welcome.

I would love to improve this, but probably will not be able to until Ledgeracio is finished.

the proc-macro-error crate is nice. I used it in a proc-macro today, really makes for a better ux. it should be easy to move to start using it, just replace panic! with abort! and unwrap with unwrap_or_else(|| abort!)
