Re: Fun with Prototypes

More fun for you: ;)

Some people want debug functions to disappear without footprint in production.

Like with Smart::Comments but without source filter.

Try to find a way where changing the prototype of a function &dmp will turn the call to a no op.

Your bar /#(\w+)/, @a; is already quite close, but it's still involving a division. :)

Isn't this sufficiently clear? `use constant DEBUG => 0; use Data::Dumper; # ... warn Dumper($myvar) if DEBUG;` [download] Or PerX::Assert.	[reply] [d/l]

an example avoiding a sub-call, unfortunately the division in void context is not optimized away. <Reveal this spoiler or all in this thread> and the warning will create runtime overhead, too :/ update But I think a little overhead is acceptable when debugging. another edge case are empty arrays causing a division by zero... update: fixed minor bug Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :) Je suis Charlie!}	[reply] [d/l] [select]
