p [a,b,c,d]
end
foo(1,2)

What strange syntax. Matz Ruby supports it, though I wouldn't say that it meets the principle of least surprise:
$ ruby -v
ruby 1.8.6 (2007-09-24 patchlevel 111) [universal-darwin9.0]
$ irb
irb(main):001:0> def foo(a=b=1)
irb(main):002:1> p [a,b]
irb(main):003:1> end
=> nil
irb(main):004:0> foo
[1, 1]
=> nil
irb(main):006:0> foo(2)
[2, nil]
=> nil
irb(main):008:0> foo(2,3)
ArgumentError: wrong number of arguments (2 for 1)
from (irb):8:in `foo'
from (irb):8

- → State changed from “new” to “open”
Opening and hoping that someone knows how to guard the spec correctly. Running the spec as is will print an error trace but won't throw an error that a lambda/mspec can catch, so it's not "taggable" as failing. Maybe tag by hand?

The specs were pushed in 6c187da3 by Peter Burns and fixed in a subsequent check by Daniel Luz in 563ff524.

closing since the specs were pushed... we can track from there. thanks! (also, ick!)
