in thread What is the correct definition of False and Null in Perl?

> 0.0 is not quite the same as 0E0.

I was talking about strings not literal numbers:

DB<105> p !! "0.0" 1 DB<106> p !! "0E0" 1 DB<107> p !! 0E0 DB<108> p !! 0.0 DB<109> p 1 + "0E0" 1 DB<110> p 1 + "0.0" 1

and by the way IMHO thats all hardly necessary.

Can't think of a use case which can't be solved by calling a function in list context.

Cheers Rolf

    Well that may be true. But the issue here is what did the other guys do? When we use an interface, we have to deal with it.
