So then, what if your committee, who happens to have the esteemed Larry Wall 
as an advisor, decides that Perl *is* the appropriate language?  What will 
happen to *your* precious ideas about which language is more appropriate?  
This is the basic problem with committees making such decisions - you, whom I 
assume to be an excellent teacher - will be forced to abandon what is working 
well for you in favor of an idea foisted upon you by people who are at least 
one step removed from the actual teaching process.

What if Python isn't on the list either?

My point exactly.  Committees and policies are dangerous things and once they 
are institutionalized, they tend to lose focus on what they were designed to 
do and instead merely more red tape for teachers to fight through.
