Re: copy pasting sweet expressions

SUBLIST works nicely for many cases, as already noted.  In addition, you can just
copy/paste and then insert/remove indentation; that's actually easy to do.
I did it many times when writing my "sweeten" program using sweet-expressions.

That'd be awesome!  I think you can count on that, once it's had more public review.

I think it's important that this SRFI be widely implemented,
especially in widely-used Scheme implementations like Racket.

I think the key is that there be some standard "start sweet-expressions" marker,
be it #!sweet, #!lang sweet, (srfi 110 engage-warp-drive), or whatever.
I want it to be possible to move code, unchanged, between implementations.
The current draft uses #!sweet, on analogy with #!fold-case...
but we're not married to that.

If some marker is much easier to use (or preferred) than another in some
Scheme implementation, then PLEASE let us know!
