Well, that's kind of in the eyes of the beholder, right? You could argue 
about prefix vs. postfix (Forth/postscript) and never get out of a 
religious war. I fully appreciate the value of s-expressions but maybe 
not everyone else does. Or are you saying that Haskell is broken because 
it doesn't use parentheses?

Sure, and that's what I've done on other projects. But that implies that 
the data ("program source") still has to be essentially in an 
s-expression format or some trivial mapping thereof.

Yeah, that's one way to look at it. But I don't think replacing a 
"<scheme></scheme>" pair of tags with a pair of parentheses is going to
be sufficient.
