To Bob's point about scripting languages--I like his definition and agree with 
him from a purist perspective, but suspect that a practical definition of 
"scripting language" simply means it has good OS integration, i.e., it's easy 
to do a bunch of commands, maybe get back results in program variables, stuff 
like that (with the degree of those functions varying between scripting 
languages).

I'm sure we've all spent far too much time using some NON-scripting language 
and Googling, trying to figure out "How the heck do I issue this simple system 
command--I don't even care about the result beyond maybe a return code?" and 
that's often surprisingly difficult. With the things that people call 
"scripting languages", that's always super-easy.
