--- !ruby/object:RI::MethodDescription aliases: [] block_params: comment: - !ruby/struct:SM::Flow::P body: Invokes the block, setting the block's parameters to the values in <em>params</em> using something close to method calling semantics. Generates a warning if multiple values are passed to a proc that expects just one (previously this silently converted the parameters to an array). - !ruby/struct:SM::Flow::P body: For procs created using <tt>Kernel.proc</tt>, generates an error if the wrong number of parameters are passed to a proc with multiple parameters. For procs created using <tt>Proc.new</tt>, extra parameters are silently discarded. - !ruby/struct:SM::Flow::P body: Returns the value of the last expression evaluated in the block. See also <tt>Proc#yield</tt>. - !ruby/struct:SM::Flow::VERB body: " a_proc = Proc.new {|a, *b| b.collect {|i| i*a }}\n a_proc.call(9, 1, 2, 3) #=&gt; [9, 18, 27]\n a_proc[9, 1, 2, 3] #=&gt; [9, 18, 27]\n a_proc = Proc.new {|a,b| a}\n a_proc.call(1,2,3)\n" - !ruby/struct:SM::Flow::P body: <em>produces:</em> - !ruby/struct:SM::Flow::VERB body: " prog.rb:5: wrong number of arguments (3 for 2) (ArgumentError)\n from prog.rb:4:in `call'\n from prog.rb:5\n" full_name: Proc#call is_singleton: false name: call params: | prc.call(params,...) => obj prc[params,...] => obj visibility: public
