I just noticed this:

irb(main):001:0> s = "Robert Klemme"
=> "Robert Klemme"
irb(main):002:0> s[/(?\w+)\s+\w+/, :first]
TypeError: can't convert Symbol into Integer
from (irb):2:in []' from (irb):2 from /opt/bin/irb19:12:in '
irb(main):003:0> s.match(/(?\w+)\s+\w+/)[:first]
=> "Robert"

IMHO it's just a small glitch but I believe for consistency reasons we should allow for a symbol as second argument with String#[] as well.

This will be implemented in Ruby 1.9.2.

Thanks for the update! I wonder whether closing is the proper resolution. Shouldn't we be setting target version to 1.9.2 and keep this open until the code change is done?

"will" means 1.9.2 is not released yet; the code is already in trunk.
