Hi,
two quick questions:
Are multi submethods allowed?
my $x = undef;
my $y = $x.some_method;
# $y now contains an unthrown exception object, saying that undef
# doesn't .can("some_method"), right?
say $y; # Only now it dies, correct?
This is important if you have a sub which may either return a custom
object or undef:
my $x = sub_which_returns_an_object_or_undef();
my $y = $x.some_method;
One builtin example is "caller":
my $x = caller(5555); # undef if there's no such stack frame
my $y = $x.line; # unthrown exception object
