Add headings/hints to RubyVM::InstructionSequence#disasm
As the official document mentions, this method will return a String with the human readable instructions. However, it is quite hard to read since we can not understand the definition of each column, for example:
puts RubyVM::InstructionSequence.compile("[4, 5].max").disasm == disasm: #<ISeq:<compiled>@<compiled>>================================ 0000 trace 1 ( 1) 0002 duparray [4, 5] 0004 opt_send_without_block <callinfo!mid:max, argc:0, ARGS_SIMPLE>, <callcache> 0007 leave
There is no clue can inform us that "( 1)" stands for the line number, is it possible to either improve documentation or add some hints to the output string?
