Possible additional example for truth table

[spk57]

Thank you for writing Match.

I like using it to clean up confusing if then else scenarios. It enables very clean readable code.
I put together this potential pattern to use match to dispatch actions based on truth table values.

#DispatchPattern.jl
"""Implement a pattern for dispatching actions based on Truth table values using Match.jl"""

module DispatchPattern
using Match

"Basic truth structure"
struct Truth
a::Bool
b::Bool
end

"Actions for Dispatch"
actionAB() =println("Do A and B")
actionA!B() =println("Do A not B")
action!AB() =println("Do B not A")
action!A!B() =println("Do nothing")

"Pattern for dispatching based on multiple truth cases"
dispatch!(item::Truth)=@match (item.a, item.b) begin
(true, true) => actionAB()
(true, false) => actionA!B()
(false, true) => action!AB()
(false, false) => action!A!B()
bad => println("Unknown dispatch: $bad")
end

truths=[Truth(true, true),
Truth(true, false),
Truth(false, true),
Truth(false, false)]

map(dispatch!, truths)

end
