[plt-scheme] 352.5

MzScheme and MrEd are now version 352.5 in the SVN repository trunk.

The changes are mostly internal, such as better compilation for
`call-with-values' when the first argument is an immediate `lambda'.

In addition, `for-each', `andmap' and `ormap' now tail-call the given
function on the last argument(s) of the given list(s), and `eval'
evaluates its argument in tail position.


For your amusement, I've updated the benchmark results:

There are no big performance changes, but there are a few new
benchmarks, and it's easier to compare two implementations by
normalizing the table one of them.
