For all of Tcl's warts, it is an essential element of what makes Pd so  
great.  It is not an application but instead a flexible, open-ended  
platform, especially when you consider things like toxy.  Writing the  
GUI in OS-native C would change that.  I don't think some optimization  
is worth the loss of flexibility.  CPUs are only getting cheaper.

Using ReBirth is like trying to play an 808 with a long stick.
