I’m just working on some practice problem set, not exactly bioinformatics. :laughing:

There is quite a bit of literature on first-class continuations, defining many different flavors of control operators, and it is often possible to define some control operators in terms of others. It appears to me that Racket has a very general and expressive set of control operators, since many of the operators from the literature can be implemented in terms of Racket primitives. Is it the case that Racket provides the most general control operations, and, if not, where might I look to learn about more general operators?

You can take a look at https://github.com/racket/racket/blob/master/racket/collects/racket/control.rkt to see how they are implemente
