Re^2: Dynamically Changing Packages w/out Eval

A lot simpler and a lot less fragile:

my @overload = ('+' => sub {
    my $self = shift;
    my ($other, $info) = @_;
    # do some stuff
});

eval "package $namespace; use overload \@overload; 1"
    or die $@;

I thought the original question was how to avoid eval :)	[reply]

True, but he wanted to avoid `eval` "because it obfuscates the code". It's clearly the opposite here.	[reply] [d/l]

I avoid eval out of habit. Even if you make sure that you don't eval user input and keep the evaluated code minimal, it's still annoying to debug warnings like "Argument isn't numeric at eval 2718, line 314". Though you're right that my code looks a bit obfuscated.	[reply]
