	Simple active pattern implementation.
	You can give a qualifier in the first argument of `@active` to customize its visibility in other modules.
	```julia
	@active F(x) begin
	if x > 0
	nothing
	else
	:ok
	end
	end
	@match -1 begin
	F(:ok) => false
	_ => true
	end # true
	@active public IsEven(x) begin
	x % 2 === 0
	end
	@match 4 begin
	IsEven() => :ok
	_ => :err
	end # :ok
	```

ERROR: invalid use of active patterns: 1-ary view pattern(F(x)) should accept Union{Some{T}, Nothing} instead of Union{T, Nothing}! A simple solution is:
  (@active F(x) ex) =>
  (@active F(x) let r=ex; r === nothing? r : Some(r)) end
