Ruby called a collection of blocks -
assume have built array of callable objects doing callables = [] callables << block1 callables << block2 callables << block3 callables << block4 later want call these blocks. understand can do callables.each { |block| block.call } but wondering if make simpler calling like callables.each :call i have tried code above got argumenterror. ruby support kind of syntax? you should try : callables.each &:call array#each don't accept arguments. that's why, when write callables.each :call , :call symbol passing method each argument. when prefixed :call & , each knows giving block argument, work.
