here strings

    Hands off here strings, you unprincipled boors!  Real Example time...:

    	for (f in *) mv $f `{tr A-Z a-z <<<$f}

As opposed to

    for (f in *) mv $f `{echo $f | tr A-Z a-z}

?

I don't think I quite understand the point of here strings.  Actually,
I was a little surprised to discover that there was a seperate
primitive for here documents.  I assume this is to preserve the here
document's distinct quoting semantics?  Would it make sense to modify
the parser to emit (semantics-preserving) echo commands in order to
eliminate $&here?

    OK,
    John.

Ok by me....   :-)
