[REBOL] Re: to block! or to-block

Hi, Ammon,
Sorry to be so slow in responding...
We're getting ready for a wedding (my older son) and in crunch mode
at work, so spare time is in short supply right now.

No need for benchmarks. "Use the SOURCE, Luke!"

Based on the above, I'd expect no evaluation differences, but
using the to-foo forms adds the overhead of a wrapper function
to every eval. Hardly worth it to save one keystroke, IMHO.
