Neither, actually -- callcc is present in both 1.8.7 and 1.9, but was moved from the core to a stdlib in 1.9 (the 'continuation' module).

However, callcc is not guaranteed to be present in all implementations (and is in fact not present in JRuby and MacRuby).

I use callcc as the basis for the (mostly humorous/proof-of-concept) "reconsidered" gem, which -- to the original poster's question -- adds a limited form of goto to ruby, and for the more serious ambit gem, which provides nondeterministic programming for Ruby, and is the basis for the in-progress rulog logic programming system for Ruby.

See:

	https://github.com/jimwise/

for more on reconsidered, ambit, and rulog.  :-)
