[Templates] hash virtual method issue

[mguckeyson]

H’lo folks,   Assuming I have a hash ref $foo passed to TT2 as foo, why would foo.size return undef? And foo is not empty… I foreach through it immediately after... Any scalar returns a 1, which I understand is because scalars are cast as lists for list virtual methods.   I originally ran into this issue while trying to find a reasonably intelligent way to deal with nested hashes with foreach(es)… some of the values are scalar and need to be dealt with as such, but I’m really looking for a way to test if the value is a ref and handle it appropriately if it is.   Basically, I want the following data structure to be printed out: $foo = {           key => value ,           key => value ,           key => {                    key => value ,                    key => value ,           } ,           key => value , };   But at this point I’d settle for an explanation as to why size doesn’t seem to be behaving…   Thanks, mark
