All the problems that I was aware of have been fixed and committed to
the trunk: temporary destabilization happened on a branch and merged
back later, so I don't expect any major interruptions on the quality
of our code on trunk.

Some code fragments which I will commit to the ANSI tests later, were
failing before the changes and succeed afterwards now.

The main difference is that the current lexical environment is now
copied when a closure is spawned; before, the lexical environment
wasn't copied and therefore open to modification/clobbering.

The other fix - also important - is harder to describe in 15 words :-)

Bye,


Erik.
