Actually - whether or not I understood the [2:-2] notation, knowing nothing else, the "seq" would clue me in that we're probably doing something with sequences... Personally, I like lambdas less than regular expressions (of which I'm particularly UNfond but understand their usefulness at times). At least with regular expressions - I know that the gibberish I need to decipher (probably) has to do with text parsing... With class and def, I at least have a *name* to start with - class Square pretty obviously is going to have something to do with geometric shapes, I would hope (or maybe with boring people...). def getfoo() tells me I'm the function is likely to go elsewhere and get something. It's a *start*, a handle, to deciphering whatever the following statements are doing. (Yes, I realize that often class and function names suck - but more often than not, they give *some* clue). Whereas, with lambda - I have *nothing* to go on. With lambdas, all I know is that the programmer wanted to hide whatever it is the program is doing behind the curtain... (at least that's the way it comes across). So, not only is the word itself not descriptive of anything to me - even knowing that it means "anonymous function" - the use of it precludes descriptiveness, as compared to defining a function.
