Simplified syntax of unit type enums and options

[thelordgiveth]

A small set of edits to syntax of enums and options exercises with empty 'unit type' ()

My personal solutions compiled with these small edits

I intend to also submit a PR to the Cairo Book to make the same readability changes for unit types in 6.1 'The option enum' and 6.2 'The Match Control Flow Construct'
Thank you for providing and maintaining this excellent resource

Hi @thelordgiveth,
I feel this makes it a bit more confusing to do the exercise when you have to add args to your enum arm...

awesome, totally makes sense!

On the opposite I always thought it was confusing to force the use of the Unit type - which is only used when no meaningful value could be returned. Good coding practices force you into not associating a useless unit type to empty enum variants

Totally agree. But in the removed unit types they have to add syntax themselves. Which is still fine.

Thanks @thelordgiveth!
