Psyco == tracing optimization?

[Paddy]

Just wondered if this:
http://arstechnica.com/news.ars/pos...get-massive-javascript-performance-boost.html,
is a new name for what is done by Psyco?

- Paddy.

AFAIK, the same logic used in runtime optimization of several other
dynamic languages or shell-scripting languages (including Perl), for
quite a while.

Trace trees are widely used? Got any references for that?

I too feel that if Perl had such optimizations as Psyco gives Python
then they would shout about it.

I wonder about the new term and if it fits in the same 'box' as what
Psyco does, for example, who was aware of whose work?
