Expanding on this thought:
I see no problem omitting $@ entirely in the context of a
well-designed try/catch syntax that doesn't need to park the exception
in a temporary variable (e.g. if 'catch FOO' catches any exception
that isa 'FOO'). However, if the exception needs to be parked in a
global, I'd park it in $@ for consistency with what happens outside
try/catch.
I'd also probably be happy with something that moved us away from
keeping errors in globals entirely during exception handling and just
passed them as arguments to handler blocks. E.g.:
try {
risky()
}
catch error::io, error::network {
my $err = shift;
# do something useful
...;
}
otherwise {
log_this( shift );
}
finally {
clean_up();
}
