[r6rs-discuss] Raise-continuable and raise question

[Thomas Lord]

CLU had a clue in all of this.   In essence, it augments the range of 
all procedures with error types and gives a special, simple, pattern 
matching syntax for handling error-type returns.    The implicit default 
handler for an error return does, in fact, re-raise an error -- and so 
is similar to dynamic exception handlers -- but always converts a 
re-raised error to an error of type "unhandled", thus making far, far 
more sense in terms of how modularity relates to PL design.   Dollars to 
donuts that popular Java libraries have yet undiscovered vulnerabilities 
because Java uses dynamic handlers rather than just error returns.
