There's no particular support for that right now.


In cases where I need a rule to map over files with the same suffix,
I've used `map` to generate a rule for each file. So, normally, I'd
have a list of ".pdf" files, and then I'd map a rule template over that
list to generate a list of rules:

 ...
 ,@(map=20
    (lambda (.pdf)
      (define .fo (path-replace-extension .pdf ".fo"))
     `[:target ,.pdf (,.fo)
                ,(lambda (dest token)
                    (shell/wait "fop -c cfg -fo" .fo "-pdf" dest))])
    pdf-files)
 ....

Using `map` is not the same as having a suffix rule, because it
requires the list `pdf-files` to be written down. Arguably, explicitly
defining a list like `pdf-files` is a good practice for the makefiles
that Zuo was designed to replace.


But there are cases where a suffix rule would be a good choice, and so
I'm not opposed to adding support. I'm tempted to work on this, but I
should do some other things right now, so here are a few thoughts in
case someone else is interested to try.

The `target` and `build` layer is flexible enough to support this
addition, but things like `build/command-line` and `find-target` are
not. I imagine that functions like `find-target` that expect with a
list of `target`s would need to handle something more general --- maybe
a `(list/c (or/c target? target-generator?))`. Most of the work is
probably in `make-targets` to set up target generation.
