------------------------------------+---------------------------------------
Under all version of Ruby, you can use the binding associated with a block
for further evals. This appears to segfault MacRuby 0.4:
{{{
~/projects/jruby ➔ macruby -e "def foo(&b); eval 'a = 2', b.binding; end;
a = 1; foo {}; puts a"
-e:1: [BUG] Bus Error
MacRuby version 0.4 (ruby 1.9.1) [universal-darwin9.5, i386]
