Subject: [ruby-changes:47243] nobu:r59358 (trunk): vm_eval.c: rb_lambda_call
nobu 2017-07-18 17:31:02 +0900 (Tue, 18 Jul 2017) New Revision: 59358 https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=59358 Log: vm_eval.c: rb_lambda_call * enum.c (enum_collect): make the block arity same as the given block. [Bug #13391] * internal.h (vm_ifunc): store arity instead of unused id. * proc.c (rb_vm_block_min_max_arity): return ifunc arity. * vm_eval.c (rb_lambda_call): call method with lambda block.
