exception system

[alexshinn]

R6RS provided a detailed exception system with
support for raising and catching exceptions, using
a hierarchy of exception types.

Do we use this, or parts of it, or a new exception
system?

[kumoyuki]

No. WG2.

[cowan]

I think we need to be able to throw errors.

[arcfide]

I believe that there may be a simpler and more unified approach to errors and exceptions then the rather involved R6RS methods. Specifically, the use of error handlers and the like serves much the same purpose without nearly as much definition.

[cowan]

WG1 voted to take no action.
