For me macros and the module system is the real killer feature of 
plt. The module system, apart from the nice abstraction facilities, makes 
it is trivial to change the language to better suite your needs. The macro 
system, especially with the excellent expansion time primitives makes it 
easy to write little languages. The two combine to give plt great 
expressive power.

I wish r6rs had a feature like #lang and some better expansion time 
support (syntax-local-value anyone?); it would be a lot easier to port 
code.
