- !ruby/struct:SM::Flow::P 
  body: Returns the number of arguments that would not be ignored. If the block is declared to take no arguments, returns 0. If the block is known to take exactly n arguments, returns n. If the block has optional arguments, return -n-1, where n is the number of mandatory arguments. A <tt>proc</tt> with no argument declarations is the same a block declaring <tt>||</tt> as its arguments.
