For anyone who didn't know, "breaking" to arbitrary places is made
simple (and efficient) with `let/ec' from the module (ice-9 control), a
wrapper around `call-with-escape-continuation':

[...]

I assume that the main reason for using this is efficiency (rather

than simplicity), because allegedly guile's continuations are rather

inefficient.

On one hand, it's good to know that (and would be even better

to be able to find it out by skimming section 6.13 of the manual),

but on the other it would be nicer if the compiler could trace the

usages of continuations and figure out whether a given one is

ever being re-entered, and optimize accordingly.
