[Feature] The input format to leo run is poorly documented, and error messages are confusing.

[christian-oudard]

🚀 Feature

Please improve the error messages in leo run.

The obvious syntax doesn't work:

$ leo run 2 2
Leo ✅ Compiled 'aleo_tutorial_4ca2101b.aleo' into Aleo instructions

Error [ECLI0377016]: Failed to parse the `run` command.
Error: error: invalid value '2' for '<FUNCTION>': Identifier must start with a letter

For more information, try '--help'.

It takes a while to find the actual syntax in documentation, and --help is not helpful.

leo run main 2u32 2u32
       Leo ✅ Compiled 'aleo_tutorial_4ca2101b.aleo' into Aleo instructions

⛓  Constraints

 •  'aleo_tutorial_4ca2101b.aleo/main' - 33 constraints (called 1 time)
