The guard-like macro in the core language is now called protect.
...
This is the recommended syntax for error-handling in Chibi-specific
programs, since it's not possible to get stack traces when using
R[67]RS guard. guard is defined separately and according to the
standard in (scheme base).

Wrapping continuable exceptions in specially tagged exceptions rather than pairs.
...
This way C functions that check for and print exceptions support them
automatically. Notably continuable errors in macro expansions, will had
temporarily been suppressed, are printed again.

Alternate guard form - evaluate the guard clauses in the continuation of the raise.
...
We need to override the current-exception-handler and still pass a thunk to be
applied on return, but this allows us to print stack traces inside guards.
