If this is really needed I would rather declare the block with
variable arguments look at this

irb(main):002:1>    blk.call( *args )
irb(main):003:1> end

irb(main):004:0> myblock = proc{ |*args| case
irb(main):005:2*    when args.empty?
irb(main):006:2>      puts "empty"
irb(main):007:2>    when args.size==1
irb(main):008:2>     puts args.first
irb(main):009:2>    else
irb(main):010:2*      p args
irb(main):011:2>    end
irb(main):012:1> }

irb(main):013:0> a &myblock
empty

irb(main):014:0> a 1, &myblock

[42, 222, 22]
