Personally, I like the yield. I understand that being forced to
rewrite code
to insert the yield is ugly, but the yield makes clear that the
control
flow is special. In Scheme there is no syntactic distinction between
ordinary function
calls and continuation calls, but they are quite different since
continuation do
not return (!). I always thought this is was a wart of the language,
not an advantage.
