go-toml V2

Development branch. Probably does not work.

👉 Discussion on github.

Must do

• Unmarshal into maps.
• Support Array Tables.
• Unmarshal into pointers.
• Support Date / times.
• Support struct tags annotations.
• Support Arrays.
• Support Unmarshaler interface.
• Original go-toml unmarshal tests pass.
• Benchmark!
• Abstract AST.
• Original go-toml testgen tests pass.
• Attach comments to AST (gated by parser flag).
• Track file position (line, column) for errors.
• Benchmark again!

Further work

• Rewrite AST to use a single array as storage instead of one allocation per node.
• Provide "minimal allocations" option that uses unsafe to reuse the input byte array as storage for strings.
• Cache reflection operations per type.

Ideas

• Allow types to implement a ASTUnmarshaler interface to unmarshal straight from the AST?
