Nonsense.
Traditionally Perl has had both the "do" and the "eval" block
forms, the latter which traps, the former which doesn't.
"try" is just a slightly souped-up "eval" that better handles the
class of problems introduced when exceptions are more commonly
used for error handling (by adding some well-defined auxiliary
clauses to the statement).
Perl has always used an in-flow statement (namely "eval") to signal
an unwind-trapping context; are you *sure* you want to change that
tradition now?
If we work together on this we can make Perl 6's exception handling
something worth having worked on. If we throw a bunch of untested
ideas together we can only hope they work (at least I hope they work,
since Perl has been my favourite language for the last twelve years).
Now, shall we?
Yours, &c, Tony Olekshy
