Description

$ ./ruby -ve 'BasicObject.new.instance_eval { ->{} }'
ruby 2.0.0dev (2012-02-03 trunk 34424) [x86_64-linux]
-e:1:in `block in <main>': undefined method `lambda' for #<BasicObject:0x007ffff847ef28> (NoMethodError)
        from -e:1:in `instance_eval'
        from -e:1:in `<main>'

I'm not sure it is a bug or not, but I think lambda syntax should work everywhere.

* compile.c (iseq_compile_each): call on special object instead of self. since stabby lambda is a syntax, so it should not be affected by the context. [ruby-core:42349][Bug #5966] * insns.def (send): no special deal for FCALL. self should be put on TOS instead.

I'm not sure why FCALL is dealt specially in op_send. It doesn't seem needed if self is put instead of nil.
