Research direction

Start by reading the implementation of the fuzz_target! macro and how it currently handles one Arbitrary variable. Compare the proposed multiple-variable syntax with the alternative fuzz_targets macro, then define which approach is in scope. Done means multiple Arbitrary variables can be fuzzed from the same input with clear macro behavior.

Written by the indexing model from the issue text.

Description

A possible upgrade would be the ability for creating multiple variables that are to be fuzzed from the same data in the fuzz_target macro.

Something like this?

fuzz_target!(|rgb: Rgb, other: Other| {})

That, or have another macro named fuzz_targets
