ssp encourages mixing your logic with your presentation, just like PHP or
ERB does.

That's fine and you don't need ssp for that.

Not at all.  In fact, it's a great way of doing things, and you don't need
ssp for that at all.  You can define the code in regular .scm files, which
can live outside the docroot (which is much more secure).

Then you can load this code from your Spiffy startup file.  If you want
reloadable code, you could look into the "system" egg for that.

 experience much like composing poetry or music."
