[plt-scheme] only 2 simple questions

After you have finished HtDP, study how the teachpacks are written just  
to get an idea what "practical" Scheme programming looks like. You will  
quickly find that PLT Scheme is a lot more than you imagine.

Practical 1: There are lots of practical applications of PLT Scheme  
(and other Scheme implementations) but not enough to create job  

Practical 2: It is always good to know how principles apply in  
different settings. Work through HtDP again when you're done and do it  
in Perl or Ruby.

Practical 3: We hope to have HtDCH out by the end of the year (or  
spring) and that'll show you how HtDP goes in Java and more.

Good luck -- Matthias
