It seems it's a regression after all; no time to fix it now, but I've found
when it happened:
ruby-trunk-12116$ ./ruby -v -e "p proc{}.arity"
ruby 1.9.0 (2007-03-21 patchlevel 0) [i686-linux]
0
ruby-trunk-12117$ ./ruby -v -e "p proc{}.arity"
ruby 1.9.0 (2007-03-21 patchlevel 0) [i686-linux]
-1
The regression was introduced in
Wed Mar 21 20:05:07 2007 Koichi Sasada <ko1@atdot.net>
* compile.c, parse.y, eval.c, intern.h, iseq.c, lex.c, node.h,
proc.c, vm.c, vm_macro.def, vm_macro.def, yarvcore.c, yarvcore.h,
debug.c, debug.h: merge half-baked-1.9 changes. The biggest change
is to change node structure around NODE_SCOPE, NODE_ARGS. Every
scope (method/class/block) has own NODE_SCOPE node and NODE_ARGS
represents more details of arguments information. I'll write a
document about detail of node structure.
PS: there's already a test in test/ruby/test_proc.rb
def test_arity
assert_equal(0, proc{}.arity)
assert_equal(0, proc{||}.arity)
...
maybe it should also be added to sample/test.rb, so it gets executed on
make test w/o requiring a full make test-all ?
