Improve developer experience and error messages

[yhyadev]

Why?

Status quo's error messages are barely helpful that it makes it easier for people to hate the language just by how the compiler communicate

How?

There are few tasks we need to achieve before this issue being closed:

• Prefer to recover and not panic on one error message
• Add helpful notes to show how should the user fix the error

Examples:

1. Recommend to use .* suffix instead of prefix with *
2. Recommend an available variable name to use instead of undeclared one (same for fields), which requires some autocorrection techniques and using the scope as the dictionary

• Print what did the compiler see to get that error
